When Jo Cox, the Labour MP for the Yorkshire constituency of Batley and Spen, was murdered on 16 June, just seven days before last year’s EU vote, the nation was stunned.

This poignant film tells the story of a kind-hearted woman who worked tirelessly for her constituents.

Yet the film also recounts the dark tale of her killer, Thomas Mair, an outsider who became obsessed with fascist propaganda before savagely lashing out.

Featuring candid accounts of Jo’s final moments, questions over what triggered Mair’s behaviour and cutting admissions from the detectives who investigated the murder, this film pulls no punches.
