The fly-on-the-wall crime documentary returns for this one-off.

When a 19-year-old man is killed by a single bullet shot through an open window in
a quiet Milton Keynes street, detectives investigate… and it’s not long before a picture
begins to emerge.

Taking the viewer from the frantic 999 call to the courts of justice, this gives a unique and gripping insight into the painstaking work involved in piecing together events that led to the fatal shot.
