Hellcats of the Navy is a movie starring Ronald Reagan and wife Nancy Davis (her then professional name) — a moral WWII submarine tale — the only film in which they appear together. Reagan is Captain Casey Abbott, commander of the fictional submarine USS Starfish, who is ordered to undertake a dangerous mission which sees him attempting to cut off the flow of supplies between China and Japan in the heavily mined waters off the Asiatic mainland. When a diver, who is Abbott's competitor for the affections of Nurse Lieutenant Helen Blair (Davis) back at home, gets into a dangerous situation, Abbott must struggle to keep his personal and professional lives separate in dealing with the crisis.
