Smith and McCann investigate a robbery involving local youth Lennie Cox. When they arrive at his flat, they find him liaising with Jurgen Holz, a Neo-Nazi criminal wanted by Interpol for drug trafficking charges. Holz manages to escape, but Smith catches up with Cox, and he is cornered by a group of black youths. As the pair catch up with Holz, they give chase, but Smith finds himself in a radio deadspot. He is then is suspected of having a racist motive when he fails to respond to an urgent assistance call from McCann, who is badly beaten by a gang of neo-Nazi skinheads. Determined to clear his name, Smith veers dangerously close to compromising an SO10 undercover operation to arrest Holz.
