In late 19th-century New Mexico, Samuel Jones reappears hoping to reconcile with his adult daughter Maggie Gilkeson. She is unable to forgive him for abandoning the family and leaving her mother to a hard life and early death. This situation changes when Pesh-Chidin and a dozen of his followers (who have left the reservation) pass through the area, ritualistically killing settlers and taking their daughters to be sold into slavery in Mexico. Among those captured is Maggie's eldest daughter, Lilly. Maggie's rancher boyfriend Brake Baldwin was among the settlers killed. The U.S. Cavalry refuses to help retrieve the captive women as its resources are tied up conducting forced relocation of captive Native Americans. This leaves Maggie, her father, and her younger daughter Dot alone in tracking the attackers. The group unexpectedly meets up with Kayitah, a Chiricahua, and an old friend of Jones, who also happens to be tracking the attackers with his son Honesco, because among the captives is a young Chiricahua woman who is engaged to Honesco. After the two agree to join the group, and Maggie treats Honesco's injuries, Kayitah informs Maggie that Jones had been a member of their Chiricahua band where he gained the name Chaa-duu-ba-its-iidan, (“shit for luck”) during his wanderings. It is finally with the combined efforts of the two families that they are able to free the women, at the cost of Kayitah's life, and immediately flee to the mountains with the kidnappers behind them. Knowing they have no other choice but to stand their ground, the group fights off the remaining kidnappers including Two Stone. During the battle, Jones fights El Brujo, the one responsible for kidnapping his granddaughter. When Brujo attempts to kill Maggie with a pistol, Jones sacrifices his life to save his daughter as both he and Brujo fall off a cliff to their deaths. Maggie shoots at the last remaining kidnappers to scare them off. She realizes her father's love for her and finally forgives him.

Jerry Maguire (Tom Cruise) is a glossy 35-year-old sports agent working for Sports Management International (SMI). He writes a mission statement about perceived dishonesty in the sports management business, "The Things We Think and Do Not Say: The Future of Our Business." Management sends Bob Sugar (Jay Mohr), Jerry's protégé, to fire him. Jerry and Sugar call all of Jerry's clients to try convincing them not to hire the services of the other. Sugar secures most of Jerry's previous clients. Jerry speaks to Arizona Cardinals wide receiver Rod Tidwell (Cuba Gooding, Jr.), one of his clients who is disgruntled with his contract. Rod tests Jerry's resolve through a very long telephone conversation, culminating in the famed "Show me the money!" scene. Meanwhile, . Frank "Cush" Cushman (Jerry O'Connell), a superstar quarterback prospect from Southern Methodist University expected to be number one in the NFL Draft, also stays with Jerry after he makes a visit to the Cushman home. Leaving the office, Jerry announces that he will start his own agency and asks if anyone is willing to join him, to which only 26-year-old single mother Dorothy Boyd (Renée Zellweger) agrees. Jerry is dropped by Cushman and breaks up with his disgruntled fiancée. He then turns to Dorothy, becoming closer to her young son, Ray (Jonathan Lipnicki), and eventually starts a relationship with her. However, Dorothy contemplates moving to San Diego as she has a secure job offer there. Jerry concentrates all his efforts on Rod, now his only client, who turns out to be very difficult to satisfy. Over the next several months, the two direct harsh criticism towards each other with Rod claiming that Jerry is not trying hard enough to get him a contract while Jerry claims that Rod is not proving himself worthy of the money for which he asks. Jerry marries Dorothy to help them both stay afloat financially and to keep her from moving away. He is emotionally and physically distant during the marriage but is clearly invested in becoming a father to Ray. Although Dorothy loves Jerry, she breaks up with him because she believes that he does not love her. Before the start of a Monday Night Football game between the Cardinals and the Dallas Cowboys, Sugar tries stealing Rod, but Rod and Jerry rebuke him. The two reconcile soon after. Rod plays well but appears to receive a serious injury when catching a touchdown. He recovers, however, and dances for the wildly cheering crowd. Afterwards, Jerry and Rod embrace in front of other athletes and sports agents and show how their relationship has progressed from a strictly business one to a close personal one, which was one of the points Jerry made in his mission statement. Jerry then flies back home to meet Dorothy. He walks in and, in front of her friends, says "Hello." He then speaks for several minutes, telling her that he loves her and wants her in his life, ending with the statement, "You complete me." Dorothy's reply to Jerry is, "You had me at 'hello.'" Rod later appears on Roy Firestone's sports show. Unbeknownst to him, Jerry has secured him an $11.2 million contract with the Cardinals allowing him to finish his pro football career in Arizona. The visibly emotional Rod proceeds to thank everyone and extends warm gratitude to Jerry. Jerry speaks with several other pro athletes, some of whom have read his earlier mission statement and respect his work with Rod. The film ends with Jerry, Dorothy, and Ray walking in the park and stumbling across a Little League Baseball game. When the ball lands near them, Ray throws it back. A surprised Jerry then comments on his natural throwing ability (and possible future in sports), much to Dorothy's dismay.
