Will their firt contact be their last?

Unfolding largely in a London storage warehouse, this drama channels a love triangle involving Noel Clarke, his estranged girlfriend and her new boyfriend into a second plot isolating several characters in a confined space with a killer. Early on, a loud, off-screen bump presages both a crashed aircraft (from which something nasty has escaped) and intermittent power outages (which lock up the premises' security system, trapping people inside). An impressive if unoriginal monster is upstaged by – spoiler alert! – a cuddly toy dog with fireworks attached. The whole thing proves unexpectedly entertaining.

London is in chaos. A military cargo plane has crashed leaving its highly classified contents strewn across the city. Completely unaware London is in lockdown, Charlie and Shelley, accompanied by best friends Mark and Nikki, are at a Storage 24 dividing up their possessions after a recent break-up. Suddenly, the power goes off. Trapped in a dark maze of endless corridors, a mystery predator is hunting them one by one. In a place designed to keep things in, how do you get out?
