Average TV-thriller takes place aboard the nuclear submarine USS Anthony Wayne. It's commander (a sturdy Leonard Nimoy) is leading the Wayne to an unknown destination for a top secret mission, but on their way his recurring headaches and seemingly ill health (and psyche) worries the crew. At the same time some major plot involving sabotage is under way... As a product of television, not bad, but it offers nothing new except maybe the enjoyement of seeing Keenan Wynn as a real good-natured hero!
