FBI Agent Mickey Flynn has been unmasked as the Red Skull, revealing
that he had killed the real Flynn and taken his place and now he intends to
steal all of the inventions at the secret lab for the Reich. Captain America is
still strapped to the lab table and Skull shoots Betsy Ross to prevent her from
freeing him. Bucky gets Cap loose and they take on the Skull who is using the
remote-controlled S.A.M. robot to fight for him. The wounded Betsy frees Drs. Todd
and Smythe while the battle goes crazy. After an exciting melee, Cap detonates
a cache of grenades which blow open the cavern wall to reveal a rocky seacoast
in Maine. But the Skull is not out yet; he reactivates the damaged S.A.M. for a
final attack. With Smythe’s advice, Cap is able to rip out the robot’s radio
receiver which sends it out of control and it seizes the Red Skull and they
plummet into the ocean. Smythe wonders if the robot had somehow gained
sentience to make it rebel against the Nazi villain….
They rush Betsy back to the base infirmary where it is
learned she is dying from blood loss and her rare blood type will make it
difficult to find a donor. Cap volunteers but the donor would likely die in the
process. Cap and Betsy share a tender moment. Later, the men hear a noise from
Betsy’s room and rush in to find Miss Vinegar dead; she had the same rare blood
type as Betsy and, in an act of atonement, she transfused her blood into Betsy.
Betsy recovers and Dr. Todd is finished testing Cap and Bucky….
Meanwhile at Camp Lehigh, a woman arrives, claiming to be
Bucky’s mother….
