One day without warning, a military transport plane crashed near Hyde Park in central London, England. The accident caused a lot of confusion in London, and no one expected what harm it would do to the locals with its top military secrets. On the other side of the city, people don't seem to care much about the causes and consequences of the accident, and angry Charlie (Noel Clarke) and his friend Mark (Colin O'Dohono Colin O'Donoghue) are driving to warehouse 24 to find his girlfriend Shirley (Antonia Campbell-Hughes) after Charlie and Shirley broke up in discord. When they quarreled face to face about the theory, the power in the warehouse was suddenly cut off and everyone was trapped in the dark contract. What makes them even more unbelievable is that some mysterious and terrifying creature is always ready to take the lives of these people during its lingering period.
