Plot In September 1942, during World War II, Susan Cahill (Dianne Foster), art director for an ad agency on Madison Avenue run by her fiance, is jealous of his business flirtation with a client's daughter to secure a deal. She accepts an invitation to dinner on Long Island from agency artist Alexander "Alec" Austen (Alan Ladd). Susan is disturbed by Alec's obvious feelings for her, but accepts a lunch date the next day anyway. After she leaves, Alec receives a telegram to report for active duty in the U.S. Navy but decides not to tell Susan as their relationship grows. Just before reporting for duty, Alec takes Susan home to meet his mother, a Quaker, revealing to them his hope to marry Susan—and his call up. His mother is hurt that Alec did not disclose his military obligation and saddened that he has disregarded the pacifist tenets of his upbringing. Susan admits she loves Alec, but will not break her engagement.

Meredith (James Whitmore), quickly takes a shine to Alec and he is befriended by his roommate and the ship's doctor, Lt. Blanchard (Efrem Zimbalist Jr.), who soon realizes Alec is "carrying a torch" for Susan. However, the ship's executive officer, Lt. Comdr. Edge (Keenan Wynn), has an immediate dislike of Alec's Quaker background and objects to his assignment as assistant gunnery officer. Alec introduces himself to the sailors in the gunnery division, catching them gambling but overlooking the offense. Chief Petty Officer "Frenchy" Shapiro (William Bendix) congratulates Alec for the way he handled the situation but receives a gentle warning that they best not repeat it. The two become close friends despite
