Joe Sharkey knows he is passed his prime. Now in his sixties, the younger surfers around the breaks on the north shore of Oahu still revere him as the once-legendary 'Shark', but his sponsors have moved on, and Joe wonders what new future awaits him on the horizon. Uninterrupted quality time with the ocean, he hopes. Life has other plans. When he accidentally hits and kills a man near Waimea while drunk-driving, he fears he will never rebound. Under the direction of his stubbornly loyal girlfriend Olive, he throws himself into uncovering his victim's story. But what they find in Max Mulgrave is entirely unexpected: a shared history - and refuge in the sea.
