NFL quarterback Joe King (DWAYNE "THE ROCK" JOHNSON) is popular and wealthy, a confirmed bachelor and a major Elvis Presley fan. However, his life is incomplete. He thinks it's because he's never won a championship, but he soon learns that he's missing something else, namely, a sense of family and commitment. His routine is drastically changed when he gets a visit from a seven-year-old daughter Peyton (MADISON PETTIS) he never knew existed.
The disruption affects his living arrangement (she makes a mess in the kitchen, needs a bedroom, and likes to dress his bulldog Spike in a ballet tutu), as well as his professional career. Although his good-natured teammates welcome the child's presence on the sidelines and even in the locker room (she stands behind a sheet when they shower), Joe's decision to bring Peyton along for the opening of his nightclub leads to an awkward moment, when he forgets her there and she's frightened amid the crowd. His pushy agent Stella (KYRA SEDGWICK) comes up with a plan to hire a nanny, but that doesn't work out either.
Much like her father, Peyton has an athletic passion, though hers is ballet. She enrolls in a class taught by Monique (ROSELYN SANCHEZ), who insists that Joe "make a commitment," by which she means he must participate -- playing a tree -- in the class' performance. Monique convinces Joe that ballet is even harder work than football, and when his supermodel girlfriend, Tatianna (KATE NAUTA) drops him, Joe becomes interested in Monique, who is a good maternal figure as well.
Just when Joe's team makes it to the championship game, he's distracted once more by the discovery that Peyton's mother is not exactly where she said she was. Now he has to make decisions, meaning the trophy and Joe's relationship with Peyton hang in the balance.
