Two sailors who are always competing against each other set their sights on the same girl. When she chooses one over the other, their friendship ends acrimoniously. However, things change when one the men is in a submarine trapped beneath the ocean and the other, a diver, is sent down on a rescue mission.
Unfortunately the movie Submarine is not yet available on HBO Max.
