During WWII, sickly Steve Rogers becomes Captain America via a secret super-soldier serum, but its creator is instantly assassinated. Relegated to a propaganda tour with theatrical sidekick Bucky Barnes, Steve's camp is ambushed by Baron Strucker's Nazi forces. Cap mounts a ferocious defense alongside a lethal Bucky and a brutal, seemingly immortal soldier named "Lucky Jim." Impressed, Sgt. Nick Fury recruits them into the "Invaders," an extraordinary alliance featuring the super-fast Whizzer, the proud Atlantean prince Namor, and a rogue synthetic android named Jim Hammond. Together, they assault a hidden mountain fortress to stop the Axis high command—Hitler, Red Skull, Heinrich Zemo, and Arnim Zola—and rescue Thomas "Toro" Raymond, a mutant boy sharing Hammond's flame powers. The assault succeeds but ends in tragedy. Bucky severely defaces Zola, driving the dying scientist to download his mind into a deadly machine that murders Bucky before being buried in the collapsing ruins alongside a crushed Zemo. Enraged, Captain America boards a nuclear jet piloted by Red Skull, knocking him out before crashing the aircraft into the Arctic Ocean. Bitter over his prior disagreements with the surface world, Namor finds Steve but chooses to permanently encase him in a tomb of ice rather than rescue him. On the fractured front line, Lucky Jim takes a bullet to the head that breaks his mind, sending him into a feral rampage into the northern woods, while a disillusioned Hammond and Toro flee into hiding. Decades later, a mid-credits scene reveals a thawed Steve Rogers awakening in a modern medical bay, greeted by a snarky Tony Stark wearing a red-and-gold mechanical glove. Finally, an end-credits scene shifts to deep space, where an experimental shuttle is bombarded by cosmic radiation before a roaring, flaming hand slams against the cockpit window.
