Early 1941, before America has entered
World War 2, Captain America and Bucky are doing battle with a band
of Nazi saboteurs. The two heroes defeat the baddies and save a
railroad bridge (and train) from destruction, then they hustle off to
a meeting with the President....
That same day in Manhattan, the
Sub-Mariner, intent on punishing America for their destruction of
Namor's undersea city, once again faces the Human Torch. After some
scrapping, Namor begins to lose his strength so he quickly dives into
the East River and away. The Torch leaves and Namor resurfaces,
listening to the conversation of a tugboat crew on the merits of
President Roosevelt. He decides that capturing the President to exact
a promise that US ships would not sail the Polar Seas would be a
good plan. Namor flies his flagship to Washington and crashes into
the White House as Captain America and Bucky are at a press event
with the President. Namor clobbers guards and Cap, snatches up FDR
and, shouting his demands, takes off in his ship. Cap pursues and
catches a hold of Namor's ship but the Atlantean spies him and turns
in the air, shaking Cap off and into the Potomac. Emerging from the
river, heads to the nearest military base and commandeers a plane,
taking off in pursuit....
Landing on a remote island, Namor
awaits America's response. FDR tries to defend America—the bombs
that ruined Atlantis were to free an exploration vessel, and no one
knew there was a land beneath—and reveals that Namor's father,
Leonard MacKenzie is still alive. The President taunts Namor for
holding a cripple (his word) hostage, and tries to persuade him to
fight the Nazis as the greater threat. Subby broadcasts his
ultimatum to the world, which attracts the attention of a nearby
German U-boat....
Cap ditches his commandeered plane
nearby then challenges the Sub-Mariner to combat. Namor and Cap fight
furiously with cap coming off much the worse against his super-strong
foe. While they are distracted, German divers snatch Roosevelt away.
When Namor sees his hostage is gone, he sets out in pursuit of the
U-boat with Cap close behind. Namor rips open the sub and he and Cap
clobber the entire crew—except for the last one, whom FDR punches
out personally. The rest of the US rescue mission arrives and Namor
decides there must be an easier way to protect his homeland and he
takes off in his flagship, saluting his two foes as he goes by. Cap
and FDR hope that someday Namor will join them against the Nazi
menace....
