What looks like a drug-related murder by Yardie street gangs on Sun Hill's patch causes Borough Commander Mannion to call in Operation Trident, who think that the gangs are trying to muscle in on the Larkmead Estate. A new scheme to encourage taxi drivers to help the police bears fruit when an overzealous cabbie brings a 'prisoner', Wesley Carter, to the station, saying he heard him making a drug deal. Checking Carter's phone reveals the number of Leroy Jones (see Borderline). Trident get PC Rickman to phone him and arrange a meeting, as her cover from their last meeting is still intact. Rickman and Jones meet at a health club, but narrowly escape with their lives after a drive-by shooting. Jones confirms Trident's suspicions about the Yardies, but he and his crew are after a piece of the action as well, Carter looking to supply whilst they do the dealing as a franchise. DC Danny Glaze is beaten up when he listens in on a meeting with Carter, but Rickman manages to convince the gang not to kill him. Worried about the rival gangs killing him, Rickman agrees to let Leroy stay at her flat.
