Trip Wit Teacher - Earl Barton (1975) - Unearthed Entertainment UN 004
Motor cycle enthusiast Jay Andrews is on a two week vacation when he stops to help two fellow bikers repair a flat tyre. Unknown to Jay, bikers Pete and Al have just been released from prison and are looking for trouble. Pete seems OK at first but he is totally under the control of his sadistic nutcase of a brother, Al. On their way to the nearest service station the trio encounter a bus taking attractive school teacher Miss Tenny and four of her female students on a field trip to Navaho country. When the bus is found broken down the brothers seem reluctant to help the girls. The girls are now alone and totally dependent on nice boy Jay and the lunatic biker brothers.
