Turner and Webb investigate when an armed robber disappears following a blag at a local convenience store. However, when CCTV shows the shopkeeper beating seven bells out of the robber with a cricket bat, the pair realise that time may be running out, and that they must find the victim before he succumbs to any harm. A vital lead in the case comes when the team identify the robber's vehicle as an abandoned scooter which Smith and Hollis dealt with earlier. Meanwhile, Heaton continues to promote his zero tolerance policy, and urges arrests for petty offences, beginning with a crackdown on crime at the nearby Penn Market - and Hardy finds a new investigative ally in Hinckley.
