The six-part drama series takes place in 1970s London and focuses on a couple who form a radical underground cell with their friends and fellow political activists.

The tension-building trailer gives a first glimpse of the central couple Jas (Freida Pinto) and Marcus (Babou Ceesay) tangled in a dangerous opposition with a racist police force, who are determined to oppress the social and political activism of the black movement.

Idris Elba (Luther), who also co-produced the series, stars as Kent, a second-generation British man seeking equality for black people through peace and intellect.

John Ridley (12 Years a Slave) wrote and directed the series, which also stars British talent Rory Kinnear (Spectre), Zawe Ashton (Fresh Meat) and Daniel Mays (Line of Duty).

John Ridley said: “Though a created narrative, Guerrilla is rooted in the realities of an era when the young and the passionate of differing backgrounds found themselves united by a struggle for the rights of people of colour, of the oppressed, the disenfranchised, and the marginalised.

"If those rights could not be obtained by way of public referendum, they would be had with the blast of a bomb, or from the end of a gun. These beliefs are personified in our lead characters Jas and Marcus.

"They are reflected, as well, in an ensemble that must deal with the consequences of their own actions – and at times in action – both for and against ‘the cause’.”

Guerrilla will air on Sky Atlantic on 13th April 2017.
