Shawn Spencer has always hated the wilderness - by which he means anything outside the delivery radius of his favourite pizza place. But Psych has been hired to solve a baffling case of industrial espionage, and the only way to catch the spy is to join their client's bonding retreat - a gruelling seven-day mountain trek. But when one of the campers turns up with a bullet in the head, Shawn and Gus soon realise that sheer cliffs, rampaging bears and freeze-dried pineapple aren't the greatest threats they face.
