An Officer and a gentleman

An Officer and a Gentleman is a 1982 American romantic drama film starring Richard Gere, Debra Winger, and Louis Gossett Jr. Zachary "Zack" Mayo is preparing to report to Aviation Officer Candidate School (AOCS) following college graduation. After his mother's suicide while he was a child, he moved to the Philippines to live with his father, Byron, a US Navy Boatswain's Mate First Class, a drunk, and a womanizer. Zack grows up as a Navy brat at U.S. Naval Base Subic Bay and is now determined—despite his father's disapproval—to become a Navy pilot.
Upon arrival at AOCS, Zack and his fellow AOCs are shocked by the harsh treatment they receive from their head drill instructor, Marine Gunnery Sergeant Emil Foley. Foley tells them that he will eliminate OCs who are found to be mentally or physically unfit for commission as an ensign in the U.S. Navy, which will earn them flight training worth over $1,000,000. He also warns the male candidates about "Puget Sound Debs", local girls who dream of marrying a Naval Aviator and who will feign pregnancy or stop using birth control to trap a man. Zack and fellow candidate Sid Worley meet two local factory workers, Paula Pokrifki and Lynette Pomeroy, at a Navy Ball. Zack begins a relationship with Paula, while Sid dates Lynette.
Foley runs the program mercilessly, and Recruit Topper Daniels drops out after nearly drowning during a ditching-escape exercise. Foley believes Zack lacks motivation and is not a team player, and when he discovers Zack has been selling pre-shined shoes and belt buckles, he punishes Zack with an entire weekend of hazing to make him quit the program. Zack refuses, and Foley tells him he will expel him. Upon hearing this, Zack breaks down and admits that he has no options in civilian life. Satisfied that Zack has come to a crucial self-realization, Foley relents.
The next weekend, Zack learns that Paula's real father, an officer candidate like him, got Paula's mother pregnant and refused to marry her. Shortly after, as it nears time for him to move to another academy for the next part of training, he breaks up with her, which she reluctantly accepts. During his last obstacle-course run, Zack has a chance to break the course record, but instead stops to encourage his teammate, Casey Seeger, to succeed. Zack attends a dinner with Sid and his parents and learns that Sid has a long-time girlfriend who was his late brother's girlfriend, and whom he is planning to marry once he receives his commission. Meanwhile, Lynette has been dropping hints to Sid that she may be pregnant with his child.
After having a severe anxiety attack during a high-altitude simulation in a pressure chamber, Sid quits. He goes to Lynette's house to propose marriage but she rejects him, telling him she wants to marry a naval aviator, and that she got her period and so is not pregnant. After Sid leaves, Zack shows up with Paula looking for Sid; after Lynette recaps the conversation with Sid, Zack accuses her of making up the pregnancy, which she denies. Zack and Paula go looking for Sid and discover that he has hanged himself. Zack blames himself and heads back to base, intending to quit, but Foley will not let him. They fight, with Zack landing several blows on a surprised Foley before the latter ends the fight and tells Zack he can quit if he wants.
