Bonfire night, South London: Sam, a trainee nurse, is making her way home when she’s accosted by a gang of hooded teenage thugs demanding her wallet and phone. That is, until a huge, flaming meteorite crash-lands into a nearby car. Sam makes her escape while the gang find themselves confronted by a rabid, ravenous extra-terrestrial with a craving for human flesh. Having killed the creature, they soon realise that this is only the beginning. There are other aliens invading the earth, and they’re bigger, stronger and hungrier. Their only chance of survival is to take refuge within the concrete walls of their housing estate block. Teaming up with their initial victim Sam and local dealer Ron, the neighbourhood’s biggest threat, they soon realise they could be the block’s only hope. It’s inner city versus outer space, and it’s about to get nasty.
