Actor James Franco is hosting a party with all of his celebrity friends, including Seth Rogen, Jonah Hill, Danny McBride, and Jay Baruchel. Everything is going great at the party until an apocalypse starts to unfold, causing widespread disaster and chaos around all of Hollywood, and trapping the friends at Franco's house. With a very literal apocalypse occurring outside, affecting the world as they know it, the friends are forced to create their own world inside his home and dwell together until the disaster passes — with limited food supply and sanity, for that matter. Superbad actors Jonah Hill and Seth Rogen are reunited in this film, bringing their on-screen charm to this new story.
