Since we heard that The First Avenger: Captain America would be set in World War II, we haven't heard much at all. All we've had has been casting rumours. Now a synopsis of the plot has been revealed.

It sounds like a potted history of Captain America, so maybe the plan is to set him up as The Avengers leader.

The First Avenger: Captain America is to be released in May 2011, just a couple of months before The Avengers film. And we already know that it will be set during World War II. Now have the full plot synopsis for the film, courtesy of Cinema Blend.

Born during the Great Depression, Steve Rogers grew up a frail youth in a poor family. Horrified by the newsreel footage of the Nazis in Europe,Rogers was inspired to enlist in the army. However, because of his frailty and sickness, he was rejected. Overhearing the boy's earnest plea,General Chester Phillips offered Rogers the opportunity to take part in a special experiment... Operation: Rebirth. After weeks of tests, Rogers was at last administered the Super-Solider Serum and bombarded by "vita-rays." Steve Rogers emerged from the treatment with a body as perfect as a body can be and still be human. Rogers was then put through an intensive physical and tactical training program. Three months later,he was given his first assignment as Captain America. Armed with his indestructible shield and battle savvy, Captain America has continued his war against evil both as a sentinel of liberty and as leader of the Avengers.

Sounds like an origins film of sorts, which would make sense. All we need now is a director, and a Captain America. Do you like the sound of this plot?
