In 1989, the teenager Mike O'Donnell is the star of the Hayden High-School. On the day of the final basketball game, Mike will be observed and may win a scholarship in college. However, his girlfriend Scarlett tells him that she is pregnant and Mike does not play the game. Twenty years later, Mike is a complete loser that blames Scar for his failures: he is not promoted to sale manager after working sixteen years in the same company; Scarlett is divorcing him; his teenagers son Alex and daughter Maggie hate him; and he is temporarily living with his best friend, the eccentric and immature millionaire Ned Gold. Mike nostalgically visits Hayden where an old janitor talks to him about second chance in life. During the night, he sees the janitor jumping from a bridge into the river and he unsuccessfully tries to help the man. Mike passes out and when he wakes up, he discovers that he is seventeen again. Further, he discovers that he has a second chance to fix his relationship with his family.

Toward the end of filming Zac Efron had appendicitis. It started out as a stomach ache but he had it checked out that night after filming and he had surgery that same night.
