The Red Skull Holding The "Cosmic Cube" And Also Plot Details!

Above is an awesome clear image of Hugo Weaving's Red Skull holding the powerfull "Cosmic Cube". Fans didn't know if the cube would be in this film or would be kept for a sequel. Well here it is guys, it's in this one.
Also, here's some plot details:

The year is 1942, and Steve Rogers is a scrawny lad who desperately wants to fight Nazis for his country but can’t because he’s been deemed physically unfit. His fate — and his physique — is radically transformed when he signs up for Project: Rebirth, a secret military operation that turns wimps into studs using drugs and assorted sci-fi hoo-ha. There’s a love interest (Major Peggy Carter, played Haley Atwell), there’s a sidekick (Bucky Barnes, played by Sebastian Stans), and there’s the Red Skull (Hugo Weaving), Hitler’s treacherous head of advanced weaponry, whose own plan for world domination involves a magical object known as The Tesseract (comic fans know it better as The Cosmic Cube).
