Ghosts and gags collide in this witches' brew of laughs, with Bob Hope as a Manhattan radio commentator who finds himself marooned on an island of the walking dead! Larry Lawrence (Hope), sought in connection with a murder he did not commit, eludes New York police by hiding in a steamer trunk. Soon the trunk (and Larry) are aboard a ship bound for Cuba, where the trunk's owner, pretty Mary Carter (Paulette Goddard), is sailing to take possession of a recent inheritance: a "haunted" castle. Sensing that Mary is in danger, Larry and his valet Alex (Willie Best) precede her to the island, which is inhabited by a ghost, a zombie and perhaps even a flesh-and-blood fiend. There's romance, comedy and chills as Hope and Goddard contend with earthly and un-earthly foes—and try to keep from ending up as ghosts themselves!
