New Year's Eve. Masters and Sim investigate an assault on a city lawyer, and suspect that he may have been involved with the racial bating of an Asian group trying to give out leaflets to students. Stamp manages to persuade a taxi driver who was witness to the attack to come forward, but then nearly ruins it by questioning his immigration status. As Masters and Sim investigate a former partner in the law firm, she is identified by the taxi driver as the person he saw attacking the victim. Meanwhile, Smith and Kapoor deal with a frustrated man who breaks into his former home, trying to deliver late Christmas presents to his children after his ex-wife refuses him access to see them.
