In 2015, a fire at a nightclub in Bucharest, Romania, leaves 27 dead and 180 injured.

Soon afterwards, the burn victims recovering in hospital - from seemingly non-life-threatening injuries - begin dying too. A doctor at the heart of the story acts as whistleblower to a team of journalists, who in turn uncover outrageous corruption in Romania's hospitals that goes all the way to the top.

One revelation leads to another as the journalists begin to find fraud on a vast scale in the healthcare system. When a new health minister is appointed, the journalists follow his attempts, in the face of monumental obstacles, to reform a system riddled with corruption.

Oscar-shortlisted and Bafta-longlisted for best documentary, Collective: Unravelling a Scandal examines the explosive impact of investigative journalism.
