 After surviving a shipwreck in reefs not signalized in the maritime charts, the famous hunter Rober "Bob" Rainsford (Joel McCrea) is lodged by the Russian hunter Count Zaroff (Leslie Banks) in his castle in an isolated island. Bob meets Eve Trowbridge (Fay Wray) and her brother Martin Trowbridge (Robert Armstrong), also survivors of another wrecked vessel and hosted by Zaroff. Soon, Bob and Eve find that they are part of a hunting game plotted by the insane Zarof where they are the prey, and they have to escape and survive until the next morning to Zaroff and his hounds.
