Well off the beaten path in the New Jersey industrial wastelands sits the ramshackle Bayview Motel. Among the guests are Jimmy and Gene, two Ohio boys heading for New York City. An automobile breakdown forces them to stay at the Bayview. Later Lenny the owner sees to it that only two more guests are allowed to register before he turns on the "no vacancy" sign. They are two women from Trenton. Shelby is trying to escape her brutal lover, a gangster. The other is her innocent cousin Mary Ann. Shelby has a valuable ring and asks Lenny to pawn it for her. She and Mary Ann then check in and decide to stay until the money comes in. For some reason, Lenny does all he can to keep the four guests from leaving. Lenny is a very odd duck and spends much time playing the motel's lounge piano wearing a tacky old smoking jacket and pretending there is an audience. It soon becomes apparent that he has secrets and that they may somehow involve the guests, who have meanwhile coupled off and happily spend their time getting acquainted. Unfortunately Shelby's violent boy friend suddenly shows up with his uncle, a prominent gangster. The mobsters' appearance brings up some old and disturbing memories for Lenny.
