A mixed bag, as suspense ultimately gives way to over the top sentimentality in a rather limp tale written by Jesse Lasky Jr.
We're stuck with an irredeemable bad guy played by Cliff Parnell, who appeared in several movies directed by John Cassavetes. He's the greedy husband of lovely Barbara Lord (a blonde TV actress whose career never took off), and he's out to kill her father, a navy commodore, to get her inheritance. He ends up choking her nearly to death instead.
Our heroes have a race against the clock to find a bomb Cliff planted on the commodore's yacht, ending up with two well-done climax scenes, followed by a very soggy finish. The on-location footage in the harbor is the episode's best element.
