Shackled

It's been 5 years since the last victim of the killer, now known as the 'The Collector', was reported missing. Whilst on a camping trip, 4 friends inadvertently stumble across the location the police have been searching for all these years, The Collector's home. The rumoured site of the killing spree. Waking up in pitch black you find yourself disorientated and handcuffed to a wall. You have unknowingly rekindled the Collector's thirst for blood. Can you escape before he returns? One room. No doors. 60 minutes. How will you escape?
