Highwater (Blu-ray)

The waves are monsters. The dangers are epic. The competitors are insanely gutsy. Or maybe just insane. But every winter, when breakers the size of office buildings topple onto the North Shore of Oahu, the worlds top-ranked extreme surfers risk injury and worse to win surfing's fabled Triple Crown. With jaw-dropping rides from big-wave warriors like ten-time world champion Kelly Slater, three-time world champion Andy Irons, the fearless Malik Joyeaux and teenage phenomenon John John Florence, it's the ultimate, adrenaline-fuelled battle of surfing's mega-stars. And it's a battle not all will survive.
