Against the vibrant backdrop of a 1960s-inspired, retro-futuristic world, Marvel's First Family is forced to balance their roles as heroes with the strength of their family bond, while defending Earth from a ravenous space god called Galactus and his enigmatic Herald, Silver Surfer.

When five friends inadvertently cause a deadly car accident, they cover up their involvement and make a pact to keep it a secret rather than face the consequences. A year later, their past comes back to haunt them and they're forced to confront a horrifying truth: someone knows what they did last summer…and is hell-bent on revenge.
