Chris has a big night out planned when her boyfriend cancels on her. She agrees to babysit for a pre-teen girl and a pubescent boy. She's settled in for a dull night when a girlfriend calls her to say she's marooned at a downtown bus station with very seedy characters around. The three plus one of the boy's friends get into the parents station wagon for a trip to the inner city. All is well till the flat tyre.
