On a winter's night, in a grubby alleyway, in a northern town, Josh, a 17-year-old A Level student, is found stabbed to death.
The police investigation soon focuses on the four people who were in the alleyway with him that night - Josh's girlfriend, Naomi and three members of a local gang, involved in drugs and violence.
The three gang members are charged but the police start to look more closely at Naomi. New evidence emerges which seems to point to Naomi.
Could Naomi be complicit with the gang? Is she a victim or a suspect? Or are the police looking in the wrong place? Soon her lawyers become Naomi's only hope of a life beyond this nightmare.
An emotional exploration of the impact of a murder on family and friends combined with the roller coaster ride of twists and turns which make for a high-profile criminal investigation and trial.
