A Royal Navy officer is offered command of a 64 gun ship-of-the-line in the year 1808. With the enemy building warships in shipyards all around Europe, Britain is straining to keep her enemy Napoleon Bonaparte and his French Navy contained.
Bonaparte makes a fatal mistake when he deposes the King and Crown Prince of Spain, his ally. When Spain revolts, our officer, Captain John Phillips, takes his ship to the Iberian Peninsula to combat the French forces and to assist the Spanish and Portuguese people in their revolt against the oppressor.
