The Making Of The Light
The Light / Y Golau is a psychological thriller. The story centres on journalist Cat Donato (Roach), who has always been fascinated by the murder of a young girl from her own town. The news of murderer Joe (Rheon) being released causes both Cat and the dead girl’s mother Sharon (Scanlan) to confront the past and the part they played. For Cat it’s a chance to write the true events surrounding the murder and for Sharon a chance to confront the man who killed her child. With so many questions unanswered, Joe’s return to the community could be a way to get to the bottom of the mystery once and for all. If Joe Thomas did kill Ela, why did he do it, and where is the body?
