Seth Rogan picks up his buddy, Jay Baruchel, from the airport and they go back to Seth's place. Jay makes it very clear that he doesn't like L.A--so when Seth wants to go to James Franco's house warming party, he doesn't want to go. He does so anyway, which is probably a good thing. You see, that night the "End of Days" happens. A giant crevasse opens up on the front lawn, swallowing most of the party goers, which include Rihanna and Kevin Hart. The survivors--Seth, Jay, James Franco, Jonah Hill and Craig Robinson, barricade themselves inside. The next morning brings another guest, Danny McBride, who was asleep in the bathtub after the party. He's trouble. He wastes precious water and food and is too obnoxious. They vote him out of the house, an action one of them will regret later. There are rapes, possessions, monsters and demons along the way. This is a very surreal movie, as hilarious as it is nightmarish.
