After being abandoned by his comically mean clown owner (Michael Jeter), playful golden retriever Buddy meets Josh (Kevin Zegers), a depressed 12-year-old whose father has just died and mother has just relocated the family to a new town. The town holds all sorts of secrets for a curious kid -- a basketball court hidden behind overgrown vines and the dilapidated fence of an abandoned church, a basketball legend lurking behind the calm exterior of a school janitor, and, most important, a rare and talented dog who can make baskets. Buddy is talented at a lot of things, but his most important talent is that he draws Josh out of his shell. The two form a fast friendship, and when Buddy makes a basket at one of Josh’s games, he becomes the team's mascot. All is well until Buddy's mean owner finds out about Buddy's talent and comes to claim him. Then Josh must decide whether to let Buddy go or try to save him from abuse.
