Stephanie Gilmore won her first world championship at age 17 on a day off from high school.

Over the next four years, she led the sport of surfing, claiming consecutive world titles as the undisputed champ until a violent turn of events abruptly ended her winning streak.

An intimate documentary, "Stephanie In The Water" chronicles Gilmore's return to the top and the costs that come along with being a five-time world champion.

Director Ava Warbrick explores the culture of surfing, growing up as a professional athlete, and what it means to be the best.
