Benedict Dacre rules the roost at his coffee plantation, although all is not plain sailing—and soon after he breaks the news that he is selling up and it is time for his family to move on, he is shot dead. As DI Mooney and the team investigate, they soon have reason to suspect all the victim's relatives. But which one of them had enough reason to pull the trigger? Meanwhile, Ruby confesses to JP she was once arrested and the Commissioner is concerned about illegal crab racing.

The team are left stunned by another murder connected to the killing of festival queen Tiana. But there is a new lead—a phone call relating to their initial suspect—so DI Jack and his officers travel over to nearby Rosalie Island, where the owner and employees of a lucrative investment company all fall under suspicion as they are questioned about the mysterious call. Meanwhile, with emotions running high, Ruby encourages her uncle, Commissioner Patterson, to show his emotional side for once.
