Bikers, Nazis, Mafiosi, and the FBI all clash in this wild and wooly exploitation picture from director Al Adamson. Mark Adams (John Gabriel) is an FBI agent who has been assigned to infiltrate an organized crime ring that has obtained a set of printing plates that will allow them to produce nearly perfect counterfeit 20-dollar bills. The plates were made in Germany during World War II, and were discovered by a radical right-wing group hoping to restore the Nazi Party to power. The American gangsters are in cahoots with a group of wealthy American neo-Nazis sympathetic to the new German cause, led by fugitive war criminal Count von Delberg (Kent Taylor); the count has in turn recruited a vicious motorcycle gang, the Bloody Devils, to do his dirty work.

In a small, US costal town with many Spanish speakers, a motorcycle gang arrives on holiday. Also in town to try to reconnect with his pregnant girlfriend, Karen, is businessman Paul Collier. Paul and a leader of the cyclists, J.J., knew each other years before, so when the gang comes upon the couple and, led by the menacing Bunny, beats up Paul and begins a sexual assault of Karen, J.J. tries to intervene: he suggests they hold cycle-riding contests, with the winner claiming Karen (he promises, sotto voce, to set her free if he wins). After the contests commence, Paul crawls away to look for help. He meets with a shrug from a cowardly sheriff's deputy; where can he turn?
