Happy Gilmore has long aspired to be a hockey player. Despite a powerful slapshot, Happy's inability to skate and his volatile behavior excludes him from being accepted by any hockey team.
Furthermore, Happy's grandma is being evicted from her home after failing to pay her taxes. After playing with some golf clubs and learning he can shoot golf balls far distances, he decides to join the PGA Tour in an effort to win money to buy back his grandma's home.
Happy's bad-boy image attracts a loyal following, but also attracts the attention of Shooter McGavin, the favorite to win the PGA Tour who is worried that Happy's rise to stardom will undermine his shot to win.
