Joe Prince means well, he really does. But he's never been good at spending his nights alone. So, in order to try to become more mature and a better person for his girlfriend Kelly, he does something he knows he shouldn't: he agrees to house-sit George Wayne's houseboat. In the middle of a reservoir Joe will have to learn how to be alone. And what can go wrong, even though from their school days George has always been the kind of guy who gets Joe in trouble? This time is no exception and George doesn't come back when he's supposed to. Poor Joe gets himself off the houseboat and he makes it home, but within days George's body has been found on the boat along with an injured dog. With Joe's fingerprints allover the place, he's the obvious suspect.
