In 1990s Łódź, Poland, the story of “skin hunters” begins as morticians and emergency workers work out a system to trade data on deaths for money.

Over a decade, "skin trading" grows into a full-blown information system that draws in more doctors, paramedics and funeral-home owners.

After a new doctor becomes director in the emergency department, he notices an alarmingly excessive use of a powerful muscle relaxant. As he teams up with trusted staff for an internal investigation, journalists are conducting their own at the same time.

2002. An explosive investigative article on the skin hunters puts pressure on local law enforcement. But as they hit a wall in finding evidence that victims were killed, one paramedic's chilling testimony emerges.
