A young couple fall under suspicion when their child goes missing and their story doesn't add up, and Warren risks his career when he makes the fundamental mistake of getting involved with a suspect's daughter.

Ron and Marty are sent to investigate a male rape case. Meanwhile, Lew and Eric are being wary of one another and Warren tries to uncover the mystery of money falling from the ceiling in a snooker hall.

When a man reports a well-known local villain for drug dealing in his street and his home is subsequently vandalized, it appears that the culprit is immune from prosecution. Ron and Marty lose a 12 year old suspect while Lewyn adopts some highly dubious tactics.

The team investigate a spate of poisoning after a stranger hands out free champagne spiked with tranquilizers to homeless people, and one of the victims is later beaten to death. Meanwhile, a shop-owner is under investigation for fencing stolen goods.

In the final episode a fourteen year old prostitute is found suffocated while Bennet humiliates herself in front of her colleagues over her tryst with Lewyn. The dead girl's mother implicates a local boxer but the case brings Warren back into contact with a former suspect, and with ex-girlfriend Lucy.
