Leela and Tony deal with a group of Asian youths who are taunting the residents of the local estates, and the police. Leela performs a stop and search, but fails to find any incriminating evidence. Later, they are called to the scene when one of the local residents has imprisoned one of the youths in a phonebox for scrawling graffiti over a police poster. However, the incident takes an unexpected turn when the resident turns out to be the leader of a local extremist group, and Tony spots Colin fraternizing with him. Meanwhile, Roger and Amber deal with the case of a young mother who is refusing to give social services access to her child, until the child's father makes a shocking move.
