Synopsis by Mark Deming
Tyrone Power made his last screen appearance before a three-year stretch in the Marines in this World War II drama. Lt. Ward Stewart (Tyrone Power) has served with distinction as the commander of a PT boat, so his uncle, Adm. Bob Stewart (Minor Watson), gives him a new and more challenging assignment aboard a submarine. Before shipping out, Ward enjoys a night on the town, where he meets and romances a pretty schoolteacher, Jean Hewlett (Anne Baxter). However, when Ward reports for duty, he discovers he'll be serving under Lt. Cmdr. Dewey Connors (Dana Andrews), who happens to be Jean's boyfriend. On leave and on land, Ward and Dewey are soon caught up in a romantic rivalry, while on duty and under the water they must work together to ferret out Nazi U-boats. Crash Dive received an Academy Award nomination for the special effects work in the film's battle sequences.
