What happens after the final girl survives a horror film? Ashley, the sole survivor of a weekend trip to a cabin in the woods with her friends, finds herself at the mercy of an FBI psychologist during an interrogation. Is she crazy, or is there more to her story?

Barry is a down-and-out-guy who takes a job at the shipping department of Technoworks, a high-tech Yuppie company. He gets invited to the house of his boss Quinn, for a weekend afternoon barbecue with some of his boss’s friends. The party gets weird, Barry plays a demented version of charades while standing on the picnic table, and the next door neighbor starts screaming racial slurs over the fence. When Jude, the widow of the ex-owner of Technoworks arrives, the plot thickens. Clues to past crimes are revealed, and the real reason for the party is discovered. But not before Barry beats the hell out of a tow-truck driver, screws the boss’s wife and wreaks havok with the neighbor. And as the title suggests, before the day is over, we will discover who is the Felon, or perhaps the people at party are all, one way or another, Felons.
