Ackland and McCann attend an RTA when a young girl is mowed down in the street. Meanwhile, Woods investigates the hijack of a heavy goods lorry, and Cryer and Hollis attempt to solve the truancy problem for the borough's schools. However, when the three cases unlikely link together, CID and uniform work together to catch a callous thief and his family trying to make a quick buck off a cartel of stolen perfume.
