During the 1700s, pirate Captain Vallo seizes a British warship and gets involved in various money-making schemes involving Caribbean rebels led by El Libre, British envoy Baron Jose Gruda, and a beautiful courtesan named Consuelo.

Burt Lancaster plays a pirate with a taste for intrigue and acrobatics who involves himself in the goings on of a revolution in the Caribbean in the late 1700s. A light hearted adventure involving prison breaks, an oddball Scientist, sailing ships, naval fights, and tons of swordplay.—John Vogel <[email protected]>

After taking control on a British war ship Captain Vallo, the Crimson Pirate, sees a money-making opportunity. Aboard the British ship is Baron Jose Gruda who has been sent to the Caribbean to stop an independence movement led by someone named El Libre. Vallo's plan is to sell the ships store of guns and powder to El Libre and then double his money by telling Gruda who and where the rebel is to be found. Things don't go quite as planned after Vallo meets the beautiful Consuelo, who just happens to be El Libre's daughter. Vallo has a change of heart and fights with the rebels.—garykmcd
