S11·E64 They All Look The Same

Loxton and Quinnan pursue a failure to stop, but the driver manages to get away and to the safety of his sheltered housing. When Loxton tries to speak to him, he discovers his housemates speak very little English and believe the incident to be an immigration raid. When they finally manage to get the man into interview, Loxton suspects he was not the man driving the car, and is furious at being tricked by an illegal immigrant.
