New Sergeant Rachel Weston arrives at Sun Hill and begins by investigating a break-in at a jewellery shop with Kezia and Mickey. After a pursuit, the robbers abandon their bike and light it on fire, but are involved in an RTC with a car. The van involved, has a history of crime after being stolen five years earlier, and it is believed it was used it as a rental for criminals. When a boy involved in the crash is found with stolen jewellery, Mel discovers he was in the van, as he is not the car driver's son. The case is turned on its head, when it appears she is the sister of the shop owner, and she was in the hold up, not the van drivers. The van occupants claim they are looking after the boy, when he ran away from his abusive father. When he goes missing, it appears his father isn't just holding his son.
