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.
Unfortunately the movie Hell's Bloody Devils is not yet available on HBO Max.
