Masters and Nixon investigate a car-jacking, and discover that the prime suspect is a well-known offender, Franny Davidson, who is already wanted on warrant for failure to attend court. Lucky for them, he is one of twenty suspects being targeted by Gold's latest undercover operation – a mock game show aimed to trap offenders into thinking they are auditioning for the chance to appear on TV. Meanwhile, Sim is asked by her parents to investigate the theft of items from their house. Sim decides to ask for Webb's assistance to avoid a conflict of interest, but after initially suspecting their long-term cleaner of the crime, Webb discovers a homeless man has been living in their attic.
