A US submarine mistakenly surfaces in the middle of a sailing regatta in Norwegian territorial waters. Harm and Mac go aboard the sub underway to investigate; they find also a series of illnesses and an injury; they suspect that someone aboard has induced the problems. An unexpected change of orders causes the boat to make a transit under the Arctic ice to the Pacific Ocean. With help from Bud at the HQ, Harm narrows the list of possible suspects, and that prime suspect suddenly does a number on Harm. Both Harm and Mac deal with him and eventually beat him at his own game. During their time at sea they work out their differences. They and the bad guy ride a helo together back to the US. Written by
