Prominent tech entrepreneur Morgan Henderson (Dominic West) and his wife, film star Carla Duval (Sienna Miller), briefly expect their decoupling to be an amicable affair – but it isn't long before that fragile peace collapses.

They lawyer up at rival firms and prepare to play dirty in what the trailer describes as "the biggest divorce trial in British legal history".

You can get a glimpse at the scandal in store right here, courtesy of Sky, ahead of War's premiere on 2 October 2026.

In the crossfire of this epic battle is promising young lawyer Johnny Warren, played by Alien: Romulus and Shadow and Bone alum Archie Renaux, who will quickly learn that "ambition is currency, betrayal is strategy and winning is everything".

A second season of War is already confirmed to be in the works, which will turn the series into an anthology, following the twists and turns of another headline-grabbing case.

The series is created, written and executive produced by George Kay (Apple TV's Hijack), with Ben Taylor (of Netflix's The Boroughs and Sex Education) attached as the lead director.

War is coming to Sky and NOW on 2 October 2026. You can sign up to Sky TV from £15 a month.
