A serial killer is prowling the neighbourhood. He is hunting people. The police can’t determine his motives and stablish what is the pattern in his choice of prey. Under a cloud of suspicion is a mental asylum’s fugitive. You are walking down the street and hear somebody’s footsteps. You want to hide at the nearest house. You walk inside. What seems to be a regular room, happens to be a trap – someone locked you inside. You have 60 minutes to get out. The clock is ticking.
