Submarine Command reunites the romantic leads from Sunset Boulevard, William Holden and Nancy Olsen. Holden is cast as Commander White, who during an enemy attack orders that his submarine dive to avoid destruction. Though his action saves his crew, it results in the death of the machine-gunner left topside during the attack. With the exception of vindictive chief torpedo-man Boyer (William Bendix), no one holds White to task for his decision -- save for White himself, who is plagued with guilt and doubt ever afterward. Helping to alleviate White's self-flagellation is his fiancee Carol (Olsen). The thrill-packed climax finds White's submarine engaged in a sabotage action against communist forces off the coast of Korea.
