Under the Thumb

Boyden investigates when an abandoned lorry leads to the discovery of a Chinese "snakehead" gang smuggling illegal immigrants into the country. When one of the owners of the lorry company is found shot and disfigured, Boyden is forced to confront an angry gunman, who manages to escape his clutches. Nixon reluctantly agrees to help him with the investigation. Taviner is given a new role as ward officer of the Cole Lane Estate, but Murphy doubts his motives when he eagerly assists an attractive resident. McAllister is forced to hold her tongue when her main witness in the rape case starts to demand perks for her testimony. Glaze unhappily finds himself on the end of a transfer into CSU.
