A chronicle of the adventures of pirate Capt. Flint, his mateys and his rivals in the early 18th-century Caribbean begins with Flint facing a mutiny, while buccaneer cohort John Silver keeps something of great value under wraps.

A partner is sought to assist in the hunt for the Urca d'Lima; Silver comes up with a solution to Billy's morale issues; a suddenly reasonable Vane makes an impression on Eleanor; and Gates is promoted.
