Dead in the Water (2016)

A runaway yacht blazes dangerously through choppy waters as two harbor detectives pursue close behind. What was to be a routine inspection turns into the detectives' worst nightmare as the two men discover murder and ultimate betrayal on the high seas. A young temptress and her controlling father have killed the latest in a string of black widow murders. But for her, the latest victim was different. She loved him. Now she's torn between saving the detective and avenging her lover's death, or staying with the only family she ever knew.
