To break a spell that's been placed on Kassim (Damien Thomas) -- the brother of his lady love (Jane Seymour) -- Sinbad (Patrick Wayne) embarks on a journey to enlist the help of a wizard named Melanthius (Patrick Troughton). But Zenobia, the sorceress who cursed Kassim, and her nefarious son, Rafi, are hot on Sinbad's trail. Sam Wanamaker directs this adventure-fantasy that co-stars Margaret Whiting, Taryn Power and Kurt Christian.
