I'd like to see...
. Steve, having just went trough the Project Rebirth, chasing Dr. Erskine's murderer, who eventually escapes and hands Nazi scientist Arnim Zola the last sample of the Supersoldier Serum, which he uses to transform Johann Smichdt into Red Skull.
. Captain America leading the soldiers into a battle against the Nazi.
. Captain America's first confrontation with Red Skull, which he looses.
. A chase scene with Steve riding a motorcycle, escaping from CIA agents who want to arrest him to disobeying the White House's orders and trying to find Bucky and Nazi agents who tracked him down thanks to the betrayal of one his friends.
. Captain America leading a group of soldiers into an Nazi laboratory where a missile is being developed. There, the american soldiers fight off the Nazi soldiers, Captain America saves Bucky, Kleiser (Red Skull's supervisor) is killed, as well as Zola and Red Skull himself (Who later turns out to be alive). Before his "death", Red Skull activates the missile and Captain sacrifices himself to stop it before it hits the White House, causing him to sink into the cold waters where he's preserved by the ice and the Supersoldier Serum.
