This made-for-television feature (which premiered on the ABC Movie Of The Week) attracted slightly more interest than usual, due in part to the presence an unusually recognizable supporting cast (including several players, such as Joseph Cotten, Keenan Wynn and Dewey Martin, who'd had real film careers, going back to the 1940's), and Star Trek's Leonard Nimoy in the lead. Nimoy plays Commander Phil Kettenring, the captain of the nuclear submarine Wayne, which has been assigned a critical, top-secret mission involving a less than completely cooperative scientist (Malachi Throne). What Kettenring doesn't know is that the Eastern bloc enemy (this being the middle of the Cold War) is already on to the mission. They've not only got a fairly clever trap set for the sub in mid-ocean, but have also infiltrated the crew at key points. As the Wayne's and her commander's problems mount, the crew begins to lose confidence in Kettenring, threatening not only the mission, but the safety of the sub.
