Bob Randall, temporarily in command of the Coast Guard vessel
Niobe, expects a promotion and the captaincy of his ship. Instead, he is
replaced by Lieutenant Mays, son of the area commander. Mays is
afflicted with a fear of the sea, although he has served well in Coast
Guard aviation. His father, however, thinks Mays can overcome his fear
by taking command of the Niobe. When seal poachers kidnap Bob Randall's
girlfriend Connie, Bob and Mays disagree about the proper means of
rescuing her and capturing the seal poachers. When Mays's inexperience
and phobia foil their attempts at rescue, Bob comes up with his own
plan.
