You wake up chained to the underground confines of a strangers' bomb shelter and he's telling you that the world has essentially ended. What do you do? Probably freak out a bit and try and check for yourself, to be honest, which is exactly what Michelle does in 10 Cloverfield Lane.
Coming to consciousness in a concrete room after getting into a car crash, her only contact with the outside world is the man holding her hostage - Howard - and another man who managed to make it into his hideaway, Emmett. To make matters worse, it's Howard's truck Michelle recognises as running her off the road - but Howard isn't forthcoming with the truth...
Throughout the runtime, we're never really sure if we can believe Howard's weird and just plain creepy behaviour, and Emmet isn't much more of a comfort as a complete unknown quantity. With Howard definitely having something to hide and world that's supposedly full of deadly gas which Michelle sees the effects of first hand, she's stuck between a rock and a hard place as to which fate is worse.
That is, if either of them are what they seem at all.
