An obscure Eastern cult that practices human sacrifice pursues Ringo after he unknowingly puts on a ceremonial ring (that, of course, won't come off). On top of that, a pair of mad scientists, members of Scotland Yard, and a beautiful but dead-eyed assassin all have their own plans for the Fab Four.

A team of allied saboteurs are assigned an impossible mission: infiltrate an impregnable Nazi-held island and destroy the two enormous long-range field guns that prevent the rescue of 2,000 trapped British soldiers.
