Brian is a 16-year-old living in Oklahoma. Though he has tried out for the schoolbasketball team, the Eagles, he has never made it, relegated to being water boy for the team. While practicing at home, Brian's sister makes a video of him injuring himself. She shows the video around school, and it is eventually seen by Connor, the star player of the basketball team. Brian takes a liking to Isabelle, a new girl at school, but is embarrassed when Connor shows the video of him to the whole school. In order to cheer him up, Brian's dad takes him to a Thunder game against the Detroit Pistons at Chesapeake Energy Arena in Oklahoma City. At halftime, Brian is chosen to shoot a half-court shot which he misses and hits Rumble, the mascot in the process. Later on, he meets Kevin Durant and expresses his desire to play just like him. When Durant signs the special editionOklahoma City Thunder basketball that Brian got to shoot the half-court shot with, a surge of energy causes Durant's talent to transfer to Brian when he hands it over. The Thunder lose the game, with Durant shooting 0-13 in the 2nd half. The next morning, Brian learns that Connor, who was at the game, recorded him missing the half-court shot and posted it online. Later that night he goes out to a carnival and sees Connor fail to hit shots to win a prize for the new girl, Isabelle. Connor challenges him to "do better", which Brian is able to do, winning a prize which he then gives to Isabelle. Meanwhile, Durant's performance declines at practices, but insists he's only in a slump. After making several impressive shots at home, Brian decides to try out for the Eagles again. The coach, impressed by Brian's new skill, has Brian replace Connor as the team captain, and they win several games. Durant's agent learns of Brian and realizes that he is the same kid who missed the half-court shot. He tracks him down and explains that he believes Brian stole Durant's talent. He arranges for Durant and Brian to practice together to try to reverse it, but all attempts fail. Shortly before the final game, Brian and Isabelle begin fighting about how Brian has changed. Eventually, Brian goes to apologize and, while watching the video of him missing the half-court shot at her house, realizes what has to be done to give Durant his talent back. He rides his bike all the way to Chesapeake Arena and finds Durant. He explains that he hit Rumble before the transfer, and theorized that was what had to happen to reverse it. Brian hits Rumble with exactly the same ball he used to shoot the half-court shot, and then repeats the conversation that he had with Durant at their first meeting. Durant gets his talent back, and the Thunder qualify for the playoffs. At the final game for the Eagles, Brian is nervous about playing because he no longer has the talent. Though he plays rather poorly, with help from the other team members, including Connor, he still manages to lead his team to a close game and taking the final shot himself, makes the game-winning shot which sends the Eagles to the state playoffs for the first time in 32 years. Brian, who is gradually getting better at basketball, is later seen playing with Durant.
While shooting the film, Durant said that the hardest part was not the acting, but rather that he had to miss jump shots on purpose for the film, to indicate that he no longer had the ability to play basketball as well as he used to.
