Texan youngster Jesse Hilts obliges when his immature, mischievous girlfriend Nicole Carrow wants to try their luck in Hollywood. They pay no attention to a yellow pick-up with mounted search-lights, even though it willfully roughs his car once. When she has used a lonely rest-room, jess is nowhere to be seen. Gradually she discovers macabre toilet graffiti are true as even the ranger in the nearby one-man station falls victim to the mysterious brute, who brings Jess's car back the nightmare way, as he does everything, and not for the first time.
