Most parents would not recommend the military movie "Black Hawk Down" for young children, but a family in Arizona is thankful their 9-year-old son is a fan of the film.

Little Tristin Saghin is being called a hero after he rescued his younger sister from drowning in the family pool. He said he learned what to do by watching "Black Hawk Down."

"[In the movie] they were, like, pushing on your chest and giving him rescue breaths," Tristan recalled.

The young boy quickly jumped into action when he discovered his 2-year-old sister face down in the water.

"She said, 'Where's the baby?' And my mom went running outside and saw her floating in the pool," Tristan said.

"He did save his sister's life," added Mesa Fire Department Captain Forrest Smith.

Tristin's parents thought he was just going through a phase, but now they're thankful for the $2 movie that saved their daughter's life.

"We've tried to turn this movie off a hundred times," Tristin's father Chris said. "He watches these scenes over and over. He dresses up like a medic and he runs around doing these things."
