The villain General Pursur has the
seriously ill Steven, son of historian Jackson Rogers, taken into
custody....
Jack, meanwhile, has unwittingly freed
the Red Skull from the Cosmic Cube and the villain, thinking that
Jack is Captain America in disguise, tries to kill him. Jack's mind
goes back to an incident in Cap's career...
...Cap was taken prisoner by the Melter
and Radioactive Man, torturing him by injecting him with a lethal
poison, to try to find out the Avengers' secret codes. Cap instead
tricks Radioactive Man into revealing the details of the bad guys'
plot and breaks free. He is rescued by more Avengers; Hawkeye and
Scarlet Witch defeat the baddies and rush Cap to a hospital while
Quicksilver searches the docks for the enemy bomb...
...Jack holds on to the fact that his
son needs him to stave off dying; the Red Skull quickly realizes his
opponent isn't Captain America and instead forces Jack to serve him.
Jack aids the Skull in his wicked scheme, asking only that the
villain help his son. Jack tells him about General Pursur's plot to
turn American citizens into sleeper agents for the Kree. The Skull
seizes control of the White House then broadcasts the details of the
plot to the public. The people rise up against the villainous leaders
as Jack's true plan is revealed: setting the Red Skull and the Kree
against one another. Jack locates his son and clobbers Pursur—who
reveals that the Kree are coming to destroy Earth to put an end to
their failed plans. Jack reveals that Steve is the key to defeating
the Kree....
