Line of Duty Season 2
Overview
An ambush leaves three officers and a protected witness dead, and the only survivor is the officer who planned the route. DI Lindsay Denton (Keeley Hawes) swears she's innocent — framed, she says, by the very people now investigating her. AC-12 can't decide, and honestly, neither will you, episode to episode. Hawes gives one of the great performances in British television: Denton is prickly, friendless, careless in her personal life and utterly relentless, and every interview scene between her and Arnott (Martin Compston) or Fleming (Vicky McClure) plays like a chess match where both sides are hiding something. Fleming goes undercover inside Denton's unit, which gets uncomfortable fast, and Hastings (Adrian Dunbar) begins to wonder whether he's picked his target or been handed one. Creator Jed Mercurio writes police procedure like a thriller and trusts you to keep up with every form, tape and timeline. It's only six episodes, dense as anything on TV, and it's the season that turned a good cop show into the most argued-about drama in Britain. You'll pick a side on Denton. You may switch it twice before the end.
