Cause of Death

Filmed over six months with unprecedented access, the series follows Dr Adeley and his team as they uncover the truth behind a series of cases.

A woman calls police worried there's water flowing out from her neighbour's front door. When they enter the house, police find a seemingly healthy man dead in the bath.

At 9.15 in the morning, a young man enters the water below a 20ft high bridge, and when passers-by pull him from the water, he's unconscious.

Blue lights flash across the faces of emergency service workers as they wrestle to keep a young man alive on a Lancashire road after a RTA.
