Harman and Hollis attend the report of a seven-year-old schoolgirl who has disappeared. Sim is assigned as Family Liason officer and immediately notices the violent tendencies of the young girl's father. As Nixon and Hemmingway organise a search party, De Costa and Perkins begin trawling through all of the known sex offenders in the area. Meanwhile, Hunter reviews CCTV from nearby shops and is angered when the shop assistant proves to be less than helpful. As Manson organises a press conference, De Costa confirms that all of the known local pedophiles in the area have alibis, and inconsistencies in the father's account of his whereabouts start to look suspicious.
