Roger Moore took a brief vacation from playing James Bond in this witty adventure drama. Rufus Excalibur ffolkes (Moore), who for some reason prefers not to capitalize his last name, is a scuba-diving adventurer for hire with a sharp mind, a quick wit, a fondness for cats, and a certain distrust of women. When terrorist Lou Kramer (Anthony Perkins) takes over an oil drilling platform in the North Sea and threatens to blow it sky high if his demands are not met, ffolkes is called in by Admiral Brinsden (James Mason) to foil Kramer's scheme before it's too late. ffolkes, also released as North Sea Hijack and Assault Force, was based on the novel Esther, Ruth, and Jennifer by Jack Davies, who also penned the screenplay ("Esther, Ruth, and Jennifer," incidentally, are the code names for the ship, drilling rig, and platform seized by Kramer in the film).
