"Cause I'm always ready, I won't let you out of my sight"

Sean and Leigh land in mortal danger after they rescue two surfers off a reef at Maui where one falls ill, and Sean becomes suspicious to the cause which may be connected to the reef. During their investigation of a local company, they end up as captives by the corrupt department head to cover up them using toxic chemicals to create a man-made reef.
