Isolation - a heart-stopping thriller, Shutter Island meets Memento

When an office worker receives a photograph of a grisly murder scene, he thinks it's a prank, not the start of a killing spree where he knows every victim.

Nigel Randolph, a solitary man suffering from mental health issues, is implicated in a macabre set of killings, drawn into a dark world of subterfuge and deception, which leaves him questioning his own sanity.

As the police investigation progresses, Randolph discovers evidence that he may have been experimented upon as a child during radical hypnotherapy sessions, and is now victim of a high-level cover-up.

Only if he can piece together what happened to him during the controversial psychiatric treatment of his youth, can he ever hope to find the truth.
