Tragedy turns to terror in Mt. Thomas when a second body is found, killed in a similar manner to the first one, and with a crucifix by the body as before. It appears there is a serial killer in town. PJ and Amy work with Garth to track down the only man with links to both girls - a masseuse who seems to fit their profile. But, while in questioning, a third victim is found giving the masseuse an alibi. What confuses the detectives is that the third victim is male which doesn't fit with their established profile of the killer, and it seems they must start at square one. Meanwhile a recently promoted Senior Constable Susie finds Jonesy is jealous of her promotion, since he too is waiting for one; and Joss and Kelly deal with a child whose dog's burn injuries have aroused suspicion at the local vet.
