Originally released in the late 1960s, SUBMARINE X-1 stars James Caan as Commander Richard Bolton, who heads up a top secret undersea mission during World War II. Bolton failed spectacularly in a previous submarine battle, losing control of his craft in a perilous fight with the Nazi's, and ultimately becoming discredited among his fellow soldiers as the submarine sank to the murky depths of the ocean floor. A subsequent clearing of his name by the military leads him to take charge of a training program for a brand new type of submersible craft, and Bolton soon heads out into a dangerous new mission. With revenge on his mind, Bolton must draw on all his experience to overcome the same foes who originally tarnished his reputation.
