The Interceptor

Marcus Ashton is a law enforcement officer who takes crime personally. He's committed and uncompromising in fighting it on the same streets where he grew up.

Ash is closer to the bigger criminals than he has ever been. The Unit has its hooks into an important drug dealer: Xavier. They're following his every move in the hope he'll lead them to someone even higher in the organisation, and ultimately to the man at the very top.

The Unit are beginning to make inroads into the criminal organisation. Ash's job isn't great for family life, but he's doing the kind of work he's dreamed of.

The Unit's war of attrition on Roach and his gang is beginning to take effect - under pressure, and low on drugs and money, they're forced to turn to a new foreign supplier, a Norwegian nicknamed the Viking.

A new batch of toxic pills has hit the market, and the police are struggling to find the source. When the Unit discover a link between the pills and the gang they're investigating, Cartwright agrees it's worth pursuing, but only if it's to further their aims of getting higher up the organisation.

After the failure of the pill operation, Roach turns to Yorkie, a violent armed robber, to solve his cash flow problems.

After his violent encounter with Yorkie, Ash returns to work at a low ebb: Lorna has thrown him out; and now Cartwright has benched him.

With Roach's identity revealed, and the villain within their grasp, the team now face the challenge of intercepting a massive shipment of drugs.
