DS Vik Singh goes undercover to a 'car cruise', where he becomes involved with a well-organised car ringing gang led by Kevin North. Meanwhile, DC Mickey Webb tries to cultivate an unofficial 15-year old snout named Tyro Shaw, in the hope that he will grass up his father, Steve Shaw. Singh poses as a car thief, and is soon in with the gang, even gaining a meeting with North's boss - Jennifer Salter. As Webb gets frustrated by Shaw's dead-end leads, Singh pushes the boy too far about his involvement with the gang. (thetvdb.com)
