Set in the 18th century, the film stars John Payne as adventurer Dick Lindsay, hired by pirate leader Charles Barclay (Sir Cedric Hardwicke) to pose as the long-lost nephew of wealthy slave-trader Andrew McAllister (Francis L. Sullivan). It's all part of Barclay's revenge scheme against McAllister, his bitterest enemy for the past 20 years. Through a series of exciting (if slightly incredible) plot twists, Lindsay manages to foment a slave revolt against McAllister and to settle the hash of Barclay. As the exotic leading lady, Arlene Dahl looks terrific in Technicolor.
