Under pressure from Supt. Chandler and the NCS to release Phil Brown, DCI Meadows convinces Moira Scott to admit to George Stubbs's involvement in the armed robbery as well as drug dealing. DC Kate Spears goes undercover as a cocaine buyer, and with some help from NCS and SO19, they catch Stubbs and his supplier red-handed with the drugs. During his interview, Stubbs makes an allegation of corruption against Supt. Chandler. Before he calls in CIB, DI Cullen convinces Meadows he's only been told half the story.
