"Navy Born" suffers from one of those inexplicable plots that can only come from a B-movie. This is because most Bs had exceptionally low budgets and were rushed into production--and the quality of the scripts just wasn't as important as it would be with an A-picture. This is because the B was supposed to be the second or lesser film in a double-feature.
The film is about a bunch of Navy pilots who serve on an aircraft carrier (I think the one show in the film was the Lexington, but I am not 100% sure). One of them has a pregnant wife who dies during childbirth. Then, shortly after, he is killed! However, before dying he tells his fellow Navy friends that the child should NOT be raised by his wife's family. So, for most of the rest of the film the Navy guys hide the kid. And, near the end, some crooks accidentally kidnap the kid--and the Navy comes to the rescue! Uggh.
As I said, the plot was pretty bad--and very contrived. It's a shame, as the production values weren't bad and the characters were reasonably likable. It's just that the story seemed rushed...and rather dumb.
