Cheating is when you're in a committed relationship and have sex with another person....It's not cheating if you live in different area codes, if you are too wasted to remember it, or if you are with two people at the same time because they cancel each other out. But it is definitely cheating if you videotape it and someone accidentally mails the tape to your girlfriend. This is what happens to Josh, who must now drag two college buddies, and one not-so-eager-kid who happens to own the car, on a raucous 1800-mile road trip from Ithaca, New York to Austin, Texas to save his lifelong romance.
