Avsnitt 3

The team investigate an amusement arcade manager suspected of recruiting young runaways as rent boys, and PC Adam Parkes is sent undercover in an attempt to gather evidence. While Parkes is drawn into the deep end, Robinson is led on a wild goose chase by one of the boys involved. When Parkes' attempt to trap the prime suspect fails, and the boy whom he is trying to encourage to give evidence starts to ignore him, he suddenly realises that he is being drawn into a whole other ball game. Meanwhile, Morgan becomes jealous when Hutchins returns from rehab and immediately applies for promotion to sergeant. Morgan confides her emotions to Vickers, who suggests that she too should apply for promotion.
