He returns to civilian life but soon afterwards, looking for redemption, applies for submarine duty. At the New London, Conn., training base he renews acquaintance with Commander Heywood (James Millican) and Lieutenant Gates (Douglas Kennedy), the skipper and engineering officers of the sub that rescued him at sea. Bingham falls in love with Navy nurse Lieutenant Susan Peabody (Dorothy Malone), daughter of Warrant Officer Peabody (Charles Winninger) and the steady girl friend of Gates. Heywood gets a submarine command at the outbreak of the Korean "police action" and Bingham and his friend, Lieutenant Graham (Bill Williams), are part of the officer's group on Heywood's sub.
