It was filmed over the course of 18 months, with intimate and unprecedented access to a police major crime unit in Bristol, but unlike previous crime documentaries it's shot as a drama.
When 19-year old Nicholas Robinson is stabbed in Bristol his desperate last breaths are heard on the 999 call before collapsing and dying. He'd never been in trouble with the police, was engaged to his childhood sweetheart and studying at college. So who would want to kill him?
It's the heart-wrenching story of a young man's senseless death, with his family's pain and the police's determination to achieve justice for them at its heart, but this time viewers are watching real life.
