... in that it is overall what I would expect from the genre and the actor. John Wayne stars as Lt. Cmdr. Duke Gifford, the first mate aboard a US Navy submarine fighting in the Pacific theater during WWII. He and his fellow submariners brave depth charges and leaky hulls while battling Japanese forces.When they make it back to base, Duke tries to rekindle the flame with his ex-wife, Navy nurse Lt. Mary Stuart (Patricia Neal), but she's also seeing Navy airman Lt. Bob Perry (Philip Carey). Ward Bond, of John Ford's stock company (although this is not a Ford film) and Milburn Stone also make an appearance.

The submarine action is exciting and well-executed, with fine miniature work and editing. Things really bog down, though, when the plot moves back to base and the tired love triangle comes to the forefront. The opening scenes, involving the rescue of a group of nuns and small children, is very corny. All-in-all, I liked the movie well enough, and I would recommend it for fans of John Wayne action films.
