I caught this under the title PHANTOM BELOW. It's a routine TV movie with the plot of a typical submarine thriller, with HIGHLANDER's Adrian Paul playing a captain who must navigate through hostile waters and figure out how to play his part during a conflict with North Korea. I watched this out of interest because it was directed by the wonderful Brian Trenchard-Smith, of AZTEC REX and TURKEY SHOOT fame, but sadly it's one of his most pedestrian efforts.
