Guardians of the Sea was shown at the 2008 Maui Film Festival, the 2008 Santa Brabara Film Festival and the 2008 Alaska Film Festival. It traces the rich history of lifeguarding, going back to the legendary Duke Kahanamoku and Eddie Aikau, in this moving tribute to Hawaii’s "guardians of the sea." The team then jumps to modern day Pipeline, where highly skilled lifeguards protect surfers from the ocean's powerful swells.
