Olivia Colman follows on from her acclaimed performance in ITV crime drama Broadchurch with a starring role in Channel 4’s gritty new drama Run.

Katie Leung (Harry Potter), Lennie James (The Walking Dead) and Jaime Winstone (Made in Dagenham) also feature in the UK channel’s latest contemporary drama serial.

Run is a four-parter that weaves together the stories of four seemingly unconnected people facing life-changing decisions in a world where choices are a luxury and survival can't be taken for granted.

In tonight's opener, Carol (Olivia Colman) is a tough single mother striving to keep her family together in a South London council estate.

When her teenage sons commit an act of random violence that results in the death of a stranger, Carol has to choose between protecting her children or doing the right thing.

Run will broadcast nightly on Channel 4 from Monday to Thursday at 10pm.
