Valentín Bravo had always been a rather fearful child, afraid of everything from heights to spiders. His father, Juan "Johnny" Bravo, raised him trying to make him fearless by making a tarantula walk on Valentin and throwing him off a high oceanside cliff known as La Quebrada. After his father locked Valentín in a crypt at a cemetery, Valentín ran away after stating that he no longer loves him. Valentín grows up to be Acapulco's local playboy and sleeps with every tourist that crosses his path. One day a former fling named Julie shows up at his doorstep with a baby girl, claiming that she is his daughter. Julie leaves the baby with Valentín after asking him for cab fare, but she doesn't come back. After receiving a phone call from Julie in which she says she is not prepared to raise a child, Valentín races to the airport to try to return the baby to Julie but fails to catch up to her before she boards her flight to Los Angeles.

Valentín leaves Acapulco with the baby, Maggie, and hitchhikes across Mexico toward Tijuana. After being turned back at the US border, he crosses by being smuggled in a hidden compartment in a transport truck along with numerous other Mexicans. Going only by a single photo of Julie in which a Los Angeles hotel is visible in the background, Valentín visits the hotel to track down Julie. However, when Maggie wanders to a nearby pool, Valentín ends up jumping out of a hotel presidential suite into the pool 10 stories below, rescuing his daughter. A movie director witnesses this event and hires Valentín as a stuntman — a job which Valentín accepts since he believes it is the only way he can support Maggie.

An unlikely father figure, Valentín raises Maggie for six years, giving her a happy, fun, and carefree home. Meanwhile, he also establishes himself as one of Hollywood's top stuntmen to pay the bills, with Maggie acting as his on-set coach and translator as Valentín still doesn't know any English. As Valentín raises Maggie, she forces him to grow up too in his large fears, though he does it only for her own fun. Meanwhile, during a visit to the doctor in which he receives an injection, the doctor confides in Valentín — with Maggie out of earshot — that the treatments aren't working. To hide from Maggie the fact that her mother abandoned her, Valentín writes weekly letters to Maggie from her, detailing various adventures and feats around the world to explain her absence. But Maggie wishes to meet her mother, so Valentín goes to his director, and looks for an actress to play "Julie". Before the casting is complete, Valentín gets a call from Julie saying that she is in Los Angeles and wants to meet.

Julie, now in a relationship with a woman, tries to be a part of Maggie's life again, along with her partner Renee who she lives with in New York City, but after a tearful departure at the airport Julie realizes she doesn't want to just see Maggie during visits and holidays. She files for custody and cites Valentín's dangerous job and lack of English skills as reasons that he is unfit to raise Maggie. Valentín's sincerity and the story of his daring ten-story jump convince the judge that he has Maggie's best interest at heart, and he awards custody to Valentin as he is the only parent she has really known. Not backing down, Julie asks for a DNA test which proves Valentín isn't the father after all. Valentín ends up losing legal custody of Maggie, but they sneak away and decide to go back to Acapulco where he reunites with his friends, although he discovers that his father died a few years ago.

Julie and Renee threaten Valentín's director to bully him into revealing Valentín's location, who repeatedly claims he doesn't know where the father and daughter are. Eventually he relents and states that Valentín has woken up every day not knowing if it would be the last day he would see his daughter, but the details are not revealed on-screen. Julie finds Valentín and Maggie on the beach and has surprisingly dropped her attempts to gain custody. Instead, the three enjoy time together as a family in Acapulco while in a voice-over Valentín narrates how doctors can sometimes discover a heart defect for which there is no cure and which could kill the patient any time. As Valentín and Julie sit on the beach with Maggie falling asleep in Valentín's lap, Maggie peacefully passes away, which reveals that she, not Valentín, was the one with the heart defect.

One year later, Valentín is seen walking down the beach, with a dog but without Julie. Valentin now understands his father's motives in wanting to give him the courage to face his fears by preparing him to meet them, and expresses gratitude to Maggie for teaching him to face life without being ready. The film ends with a vision of Maggie playing in heaven with her grandfather, while Valentin concludes that even in their absence, his father and daughter continue to teach him how to face life.
