Meet the new, improved Andrew Mayhem. He has a real job. He's a better father and husband. And he's vowed to quit accepting money from strange women in coffee shops to perform tasks that go terribly, terribly wrong. This time he's just taking a relaxing camping trip with his family and best friend. No shortcuts. The gas tank is full. The sinister warning of the crazy old man is taken seriously. Unfortunately, when you're Andrew Mayhem, you just can't help being attacked by a group of savage killers bent on inflicting ghastly torture and bringing horrific death. Relentlessly pursued through a booby-trapped forest, it's one crisis after another as Andrew fights to protect his family, loses a body part or two, and faces the single darkest moment of his entire life.
