The Barbary Coast, 1621. A mysterious vessel floats silently on the water - its hull splintered and its sails tattered and burnt. For months the Ghost Ship has hunted pirates to liberate enslaved prisoners. Now it, too, finds itself hunted. But the ship's crew hides a secret, and the stakes could not be higher. The bravest among them are not who they seem: if arrested, they will hang for their alleged crimes. Can they survive their journey and escape their fate?
