Johannes Roberts directs this British sci-fi horror. When a military cargo plane crashes in central London, carnage and chaos ensue as its highly-classified contents are strewn across the city. Unaware of the prevailing state of emergency, recently separated young couple Charlie (Noel Clarke) and Shelley (Antonia Campbell-Hughes) have asked their friends, Mark (Colin O'Donoghue) and Nikki (Laura Haddock), to accompany them to the Storage 24 depot to divide up their possessions after their break-up. When the power suddenly goes off, the friends find themselves trapped inside the depot, and prey to an alien killer intent on hunting them down one by one.
