When a body is washed up on a beach, it's assumed it must be Edward Parker, who fell from a cliff a couple of weeks before. But it is discovered to be that of Pat Duggan, son of local nightclub owner, Jimmy. Pat had been abducted twice. And, to complicate matters, the missing Edward Parker worked for Jimmy Duggan and disappeared at the same time as Duggan's son. Coincidence? Mac and Rina don't think so . . .
