Boyden recruits an SO10 officer to go undercover in order to expose an illegal poker ring running out of a local Turkish café. However, when they raid fails, the officer goes missing. As Meadows takes over the investigation, he identifies a Turkish national he failed to arrest during his days at AMIP, and discovers he has been flagged by the Drugs Squad for an importation operation. However, Meadows leads a raid on a warehouse and blows the Drugs Squad's surveillance operation. Joining forces, they discover a scam in which a deliberate crash was caused in Germany so an apparent good samaritan could have "a mate fix the car" in order to hide drugs in the chassis and smuggle it into the UK undetected. Realising the scam has been rumbled by the SO10 officer, the team fight to track him down before he's silenced.
