In the coastal town of Los Angeles, a gang of bank robbers call themselves The Ex-Presidents commit their crimes while wearing masks of Reagan, Carter, Nixon and Johnson. The F.B.I. believes that the members of the gang could be surfers and send young agent Johnny Utah undercover at the beach to mix with the surfers and gather information.

A killer is on the loose, and an FBI agent sifts through clues and learns that the bloodthirsty felon’s victims of choice are other serial killers.
