Diving In (movie, 1990)

A high school diver fights his fear of heights and diving to get onto the team. He gets onto the team, only to find that he must dive the high platform in order to compete. His problems are further compounded by social issues out of the pool. His sister is being taken advantage of by the local tough-guy, and his coach writes him off as a loser. To aid in his overcoming of his phobia, he enlists in a previous women's olympic coach, whom he falls for and crosses the line between business and pleasure. During his training with the new coach, he experiences a bad diving accident and is warned not to dive in the championship. He ignores these warnings, and enters the competition.
