From a beach near Portsmouth, Captain Quintrell observes a fleet of ships little knowing he will soon have command of a frigate and be entrusted with secret orders. Unaware of the dangers awaiting him, he sails south where sabotage, murder and the rumblings of a volcanic island pose as much threat as a broadside from a French man-of-war.
