WHEN THE COMMISSAR COMMANDS!

Captain America sits alone in the vast meeting room of Avengers Mansion, lost in thought. Although he has become the team's unquestioned leader, he feels strangely empty. He depends on the Avengers for a home and a purpose, yet he has no private life or personal identity outside the team. The recent departure of Iron Man, Giant-Man, and the Wasp has only increased his burden. Cap also anxiously awaits a reply from Nick Fury after requesting a position in Fury's espionage organization, hoping it might give him a new direction. As he gazes out the mansion window at the bustling world beyond, he wonders if life is simply passing him by. Still, he knows he cannot abandon the Avengers while the inexperienced new members still need his leadership.

Elsewhere in the mansion, Wanda Maximoff attempts to persuade her brother Pietro to accompany her to the opera. She has purchased tickets to a performance of Twelfth Night, eager to enjoy an evening of culture and theater, something she has always loved. Pietro, however, is absorbed in watching a televised circus performance and proudly reveals that he has already bought two tickets for them to attend the circus instead. Their conflicting tastes leave neither willing to compromise, and the twins reluctantly decide to spend the evening apart.

Wanda thoroughly enjoys the opera, reminiscing about how she once dreamed of becoming an actress before persecution forced her into a life of fear and survival. At the circus, Pietro is captivated by the breathtaking trapeze artists, secretly wishing he could perform such daring feats himself. Yet he knows his mutant speed would terrify audiences if revealed. During the performance, disaster strikes when a trapeze artist suffers a painful muscle cramp and loses his grip on his partner. While the crowd assumes the accident is part of the act, Quicksilver instantly recognizes the danger. Moving faster than human eyes can follow, he races into the ring, swiftly erects a safety net, and saves both performers before anyone realizes what happened. The grateful acrobats never discover who their mysterious guardian was.

Back at Avengers Mansion, Hawkeye has isolated himself in the laboratory for hours, perfecting an experimental arrow. When he finally tests his invention, the arrow emits powerful ultrasonic vibrations that resonate at precisely the correct frequency. The vibrations effortlessly lift an enormous steel safe, proving that weight can be overcome through carefully tuned sonic energy. Satisfied that his invention works exactly as intended, Clint jokingly decides the only remaining task is finding a moving company willing to relocate the suspended safe.

Thousands of miles away, the impoverished nation of Sin-Cong suffers beneath the iron rule of a brutal Communist dictatorship. Armed soldiers gather starving villagers and berate them for failing to pay taxes quickly enough. The exhausted citizens protest that they have already surrendered nearly everything they own, leaving nothing behind except their hunger. The soldiers coldly insist that these crushing taxes are necessary to pay for the government's protection. Their complaints summon the towering ruler known only as the Commissar, whose mere presence terrifies both soldiers and civilians alike.

Demanding to know who dared criticize him, the Commissar receives only fearful silence. To reinforce his authority, he demonstrates his incredible strength by lifting a gigantic boulder high above his head before hurling it effortlessly into the air. Declaring that his mighty fists will one day crush the capitalist nations, he boasts of his unstoppable power. The villagers, however, bravely reply that they never feared the Americans, who once brought them food and clothing before the Commissar seized control. Enraged by their defiance, the dictator seizes one citizen by the collar, denounces belief in American "propaganda," and forces the entire village to kneel before him, promising they will soon witness America's humiliation.

Several hours later, Captain America receives a desperate radio transmission from Sin-Cong's underground resistance movement. The frightened rebels plead for immediate help, fearing the Commissar will soon wipe them out. Cap immediately assures them that the Avengers will come to their aid. Secretly, however, he hopes the dangerous mission will also prove his value to Nick Fury and convince the famed spy that Captain America deserves a place in his organization. Unfortunately, Cap has no idea that the distress signal is actually a carefully orchestrated trap devised by the Commissar and his aide, Major Hoy, who eagerly anticipate destroying the Avengers before all of Asia.

Captain America activates the Avengers' emergency signal with his famous cry of "Avengers Assemble!" Hawkeye, Quicksilver, and the Scarlet Witch quickly return to headquarters, where Cap briefs them on the crisis in Sin-Cong. Pietro and Wanda question why the Avengers should become involved in another nation's political affairs when they are supposed to fight crime. Hawkeye unexpectedly comes to Cap's defense, arguing that freedom and justice are inseparable and that tyranny anywhere deserves resistance. The twins accept his reasoning and agree to accompany the mission. During the flight, Cap sincerely thanks Hawkeye for backing him up, but Clint dismisses the compliment with his usual sarcasm, insisting anyone could sound inspirational if they tried hard enough.

Upon landing at a Sin-Cong airfield, the Avengers are immediately surrounded by heavily armed soldiers. Realizing they have almost certainly walked into an ambush, Captain America orders the team to cooperate for the moment in hopes of learning more about their captors. Hawkeye grumbles about surrendering to men pointing rifles at his head, but reluctantly obeys. The soldiers escort the heroes through the countryside to an elaborate temple, whose lavish architecture strikes Wanda as grotesquely out of place amid such widespread poverty. Inside, the Avengers are escorted into a massive chamber where the soldiers abruptly depart, claiming the Commissar will greet them shortly.

Instead, enormous steel doors suddenly slam shut, trapping the Avengers inside. Captain America orders Quicksilver to race through the closing doorway, but even Pietro cannot beat the descending barrier. Hawkeye blasts a hole through the door with one of his explosive arrows, allowing the team to escape, only to find themselves under heavy gunfire. Captain America charges directly into the soldiers while deflecting bullets with his shield, inspiring his teammates through fearless example. Wanda uses her hex powers to disable numerous rifles, while Hawkeye narrowly saves Cap from a devastating bazooka blast. Following Cap's command to execute "Plan Seven," Quicksilver races through the battlefield in a zigzag pattern, striking enemies with blinding speed until the entire squad of soldiers is defeated.

Although victorious, Captain America warns that they have only survived the first stage of a much larger trap. Before they can locate the underground resistance, a hidden section of the temple floor suddenly opens beneath Scarlet Witch, causing her to plunge into a concealed dungeon. The stone floor seals itself before anyone can react. Pietro frantically urges immediate action, but Cap prevents Hawkeye from blasting through the floor for fear of collapsing the underground passages. Moments later, Wanda's terrified scream echoes through the temple. Ignoring all caution, Quicksilver races off alone to rescue his sister, unable to bear the thought of losing the only family he has left.

The remaining Avengers quickly catch up and discover Wanda imprisoned behind iron bars, blindfolded and bound so she cannot concentrate enough to use her hex powers. Hawkeye melts the bars with a specially designed flare arrow just as the heroes prepare to free her. Suddenly, invisible sleep gas floods the chamber. Captain America realizes too late what is happening and warns his teammates, but the odorless fumes quickly overcome them all. One by one, the Avengers collapse unconscious, helpless victims of the Commissar's carefully prepared trap.

When Captain America, Hawkeye, and Quicksilver awaken, they find themselves imprisoned in another enormous chamber where the towering Commissar personally greets them. He boasts that they have fallen perfectly into his scheme and reveals Wanda imprisoned inside an unbreakable glass cage. Major Hoy stands nearby, ready to kill her instantly if ordered. The Commissar proposes a cruel bargain: each Avenger must fight him individually while terrified villagers watch, providing a humiliating propaganda spectacle demonstrating the supposed superiority of Communist power. Although Pietro demands Wanda's release before agreeing, the villain refuses, forcing the Avengers to accept his terms if they hope to save her life.

The Commissar dons a bizarre orange-and-brown combat uniform before selecting Captain America as his first opponent. Cap attacks with everything he has, hurling his shield and delivering powerful punches, yet the giant remains completely unmoved. Laughing triumphantly, the Commissar strips Cap of his shield and crushes him in a devastating bear hug. Hawkeye volunteers to fight next, unleashing a barrage of specialty arrows, but the Commissar effortlessly swats them aside with incredible strength before knocking the archer unconscious. Quicksilver then uses his tremendous speed to wrap the villain in a massive curtain, but even this ingenious tactic fails as the Commissar tears himself free and lands a crushing blow that sends Pietro sprawling.

Realizing brute force cannot defeat their seemingly invincible foe, Captain America notices one suspicious detail: throughout the battles, Major Hoy repeatedly disappears behind a set of heavy curtains. Pretending to surrender, Cap requests that Scarlet Witch be allowed to take her turn. Once released, Wanda casually asks why Hoy keeps hiding behind the drapes. When the Commissar refuses to answer, she casts a hex that sets the curtains ablaze, exposing an enormous control console hidden behind them. Understanding Cap's plan instantly, she destroys the machinery with another hex. As Major Hoy flees in panic, the truth is revealed: the mighty Commissar is actually a sophisticated robot remotely controlled from the concealed panel. The mechanical tyrant sputters, sparks, and explodes, ending his reign of terror. Freed from oppression, the grateful villagers celebrate their liberation and hail the Avengers as heroes, especially Scarlet Witch, whose quick thinking secured their victory. While the crowd carries Wanda in triumph, Captain America reminds the people to remain forever vigilant against future tyrants who might seek to enslave them once again.
