Love Fist and Kent Paul informs Tommy that a psycho is running loose in town and he wants Love Fist dead. The band fears that he may be at the signing event down the road waiting for them to show up. So in response, Tommy decides to drive the limo down to the event to draw the psycho out. Eventually, upon arrival, he sees the psycho shooting a security guard and taking off in his Sentinel. Tommy chases him in the limo and eventually starts to ram his car until it explodes, killing the psycho.
