Tom Swift's father has completed an experimental submarine design that he expects to test in an upcoming government sponsored race and trial. However, when news surfaces of a ship, which was full of gold, that sank off the coast of Uruguay, Tom and his father quickly change course. The treasure lies on the bed of the ocean, three miles below the surface, and only the Swift submarine can make the dive - or so they thought! Soon a rival emerges from the inky depths and a battle ensues that puts the crew in peril of sinking beneath the waves forever
