What happened in the first series of Line Of Duty?

Who is Tony Gates?

The married DCI Tony Gates (Lennie James) is the cop of dreams.

He’s the seemingly squeaky clean supercop who wins prizes.

With Tony, however, not everything is what it seems.

Suspicion of his incredible record of solving crimes leads the AC-12 Anti-Corruption Unit to take a closer look at him. And the device soon discovers shady and shadier behavior.

When do AC-12 and Steve Arnott come into play in the first series of Line Of Duty?

In the first series, we see AC-12 for the first time under the direction of Superintendent Ted Hastings (Adrian Dunbar).

He recruits young officer Steve Arnott (Martin Compston) after refusing to be part of a cover-up in his division when a robbery goes wrong.

Hastings focuses his attention on Gates and puts Arnott on the case.

Who is Jackie Laverty?

Jackie Laverty (Gina McKee) is a high-flying real estate developer who has been romantically involved with married Tony Gates.

When she told Tony that she ran over a dog in a drunken hit-and-run, Tony tried to cover up the crime.

Jackie wasn’t telling the truth, however – she actually ran over her accountant after he found out she was washing money for gangster Tommy Hunter.

Hunter then brutally murdered Laverty and framed Tony.

Now Tony was in deep doo-doo.

How were members of Tony’s team involved?

After Tony became a villain to clear his name, his team – including Matthew ‘Dot’ Cottan (Craig Parkinson) and DC Nigel Morton (Neil Morrissey) – undertook an investigation into a triple homicide.

But when the AC-12 breathed down his neck, Tony agreed to work with Arnott and Co to bring Hunter down.

How did it all end for Tony?

Tony was desperate to clear his name and found himself between two stools.

An upright copper now tucked in a gangster’s pocket and a rogue agent chased by AC-12.

Although he chose to work with Steve Arnott and DC Kate Fleming (Vicky McClure), he looked forward to a bleak future.

In the final dramatic scenes, Tony knew his family would receive benefits and a lifelong pension if he were killed on duty.

Gates threw himself under the wheels of an oncoming truck.
