A murderer with severe Obsessive Compulsive Disorder is murdering women and leaving the police messages asking for help. He is also filming the murders as they take place.
It's clear that the camera is hidden because none of the victims can see it, nor are they at first aware that they are about to be killed. Meticulous research shows that similar murders have been taking place in the Buffalo area for at least a decade. The question is, who is the unsub and what was the stressor that set his rampage in motion.
Enter young Stanley, a boy who has been completely blind sinse birth. Stanley was very close by when the killer murdered his mother two years previously, but because the boy was blind and could not see the unsub, he was left untouched. Stanley has recently been adopted and we all hope for a happy future for him. His friend, Vincent, an older man whom he met through a mentoring program has been very good for Stanley but is shocked to learn that the boy wishes he had been killed at the same time as his mother.
When the BAU learn that Vincent saw his own mother being murdered and is clearly the unsub, they have to race against time to catch him as he takes Stanley to a fun fair for his birthday.
Great work by both Alex O'Loughlin as Vincent and also by young Jake Cherry who did a great job as Stanley.
