A Navy frigate fires two warning shots across the bow of a suspect yacht, which has refused to stop when ordered; the second round appears to hit the boat, and it sinks. Harm, Mac, and Bud investigate; they figure out what had happened.

Dalton tries to reconcile, but Mac says no; he seeks one last meeting, then he dies in her arms. Harm and Mac defend a CPO. A stalker captures Mac, but Harm frees her. The admiral introduces his daughter; Bud and Harriet still have trouble.
