A submarine of the US Navy rescues 10 North Korean crewmembers from the sinking of their midget submarine in South Korean waters in the Sea of Japan; six of them wish to defect. The admiral sends Sturgis to the boat to lend a hand; he deals with medical questions as well as legal ones after a viral illness breaks out among the survivors. Sturgis runs into trouble with a US Naval intelligence officer of Korean descent. Harm returns to the Navy and the JAG Corps; he stays in touch with Mattie, and he meets an underprivileged WW2-era Navy veteran with a legal problem. Harm helps the veteran, and Mac and the admiral join in doing so. Written by

At one point the skipper of the submarine tells Sturgis that the executive officer (XO) had worked three hours on the last watch bill. Aboard a submarine of the US Navy, however, the XO would not create a watch bill; instead the chief of the boat (CoB) would create it and then submit it to the XO for his approval. See more
In the opening scene three different people - the commanding officer, the officer of the deck, and the diving officer - give, repeat, and acknowledge the order to go to "periscope depth". In contrast, however, in the real world aboard a submarine of the US Navy one does not give an order to "periscope depth" but rather to a specific number of feet (from the surface to the keel) - because the periscope depth varies (even aboard one individual boat) as a function of the sea state at a given moment and as a function of the height of the viewpoint (above the surface) which the conning officer needs or wishes to achieve.
