The San Francisco area is beset by a series of seemingly random murders without motive or pattern. The police are taunted by phone calls and letters. Could the maniac be the violent truck driver, or the seemingly mild-mannered mailman, or even a cop?

Some CB Outlaws attempt to rob an armored car.

Bigfoot kidnaps some women and some bikers decide to go on a rescue mission to save them.

An outlaw motorcycle gang is headed by two couples (Bambi Allan, Jennifer Bishop, Bill Bonner and Bryan West). The gang is badly hurt by a botched robbery and the four stars, the only survivors, eventually head to Mexico, where they have to combat a gang run by a sadistic Mexican (Rafael Campos).
