A new captain takes command of his first ship only to find himself confronted with numerous problems. First there is hostility from his Chief Mate, who feels that he has been passed over for command, and from some of the crew who agree. Then there is the inflammatory presence of a woman steward, signed on at the last moment to replace a crew member who jumped ship. Worst of all is a somewhat ludicrous mutiny plot perpetrated by a couple of the engine room crew to murder the entire crew and take over the ship.

Although the plot is supposedly based on a true story the tension fails to the level that it might have done, which is probably attributable to the director rather than the cast. However, give the film full marks for it's shipboard atmosphere, which is certainly highly authentic, thanks to the fact that it was filmed aboard a couple of real merchant ships. The scenes on the bridge of Matson Line's old SS Mariposa are played pretty much as they would have been in real life, as are the subsequent scenes shot on board the freighter, which is almost certainly a Liberty Ship, of which many were still around at the time this film was made. Perhaps the only detail of the freighter that doesn't ring true is the fact that she is riding much higher in the water than she normally would have been because, since the ship was being used as a movie prop, she was obviously carrying no cargo or ballast, and very little fuel.
