The missing man is a Silicon Valley big shot known to all as the Big Kahuna. Nick and Kate's only lead takes them to Hawaii, where the missing man's free-spirit, drop-out son spends his days looking for the perfect wave and his nights puffing weed. To get close to the Kahuna's son, Kate and Nick go undercover as a married couple in the big-wave surfer community on Maui's North Shore. Living a laid-back, hippy-dippy lifestyle isn't exactly in Kate's wheelhouse, but the only thing more horrifying is shacking up with Nick Foxéven if he does look pretty gnarly on a longboard. If they don't catch a break soon, waves aren't the only thing she's going to be shredding (or bedding).
