When a rural English community of the 1930s is the victim of an alien invasion, the residents' lives are upended by the harsh realities of life-and-death violence. Led by the town's outsider and retired war veteran, they will have to rally together to uncover the secret of their invaders and ultimately fight back.
With nowhere left to run, our heroes must band together in a desperate bid to take down the largest alien they have faced yet and save whatever is left of Lower Crowchurch. But is there hope of safety even if they succeed?
