Boyden is shocked to discover that someone has been impersonating him, raiding illegal poker games and pocketing all the cash, and decides to go undercover as a punter to trap him. However, during the operation, the technology provided by the yard goes haywire and all of the suspects manage to escape without capture. Meanwhile, as the phony Boyden attacks and robs a prostitute, the real Boyden finds two Yardies on his case set out for revenge. As a second operation is organised, Boyden asks one of the players from the first game to go undercover and catch the fake police officers in the act. However, having gotten the Yardies on his side, Boyden organises sinister revenge for his fake counterpart.

Smithy and Rickman attend a break in at a primary school and find a seven-year-old boy looking for food. Further investigation reveals that the boy has been living alone for three days and his parents are nowhere to be seen. Interviewing the family's friends and relatives, Deakin discovers that it is very unlike the parents to just disappear without trace, and CCTV footage shows a van watching the family's house on the night of the disappearance. Blood found in the family bedroom indicates the parents may have been harmed, but Deakin is furious when a racial attack on the restaurant where the boy's father works is found to have been investigated by Smithy over a week previously.
