From the official synopsis:
Long ago, Steve Rogers (Matt Salinger) was a true American hero, a brave super soldier created by scientists to help the Allied Forces fight for freedom in World War II. But during a battle with the sinister Red Skull (Scott Paulin), he was lost, entombed in ice. Decades later, his body has been found and revived and Steve must again don the mantle of Captain America to help save the President of the United States (Ronny Cox) — and the world — from his arch-nemesis once and for all.
“Captain America” will be available on Blu-ray from Shout! Factory on May 21.
