Nixon and Turner investigate the hijacking of a heavy goods lorry which results in the theft of £150,000 worth of computer chips, as well as a substantial amount of other electrical goods. However, when they find half of the missing haul in a lock up belonging to an employee of the company, they realise that the computer chips may not have been aboard the lorry in the first place - and must stop the business directors eloping with a tidy profit. Meanwhile, Manson is forced to intervene when James Tennant commits a burglary, convinced he has found the hiding place where Amy is being kept, and Walker is reprimanded for continuing the investigation into serial rapist Keith Durante.
