For a decade, brilliant scientist Robin Goodwin has cleaned up ocean pollutants and bred corals to fight climate change with their growing fleet of upcycled tankers. All goes well until, isolated in the North Pacific Gyre by a freak storm, Robin finds a body in a coral tank and is presumed to be the killer. Owner and crew must solve the mystery before the storm ends and authorities arrive to arrest Robin, impound the ship, and cripple the fleet.
