The residents of a cul-de-sac community in The Wirral are plunged into a horrifying world of violence, terror and paranoia when suddenly surrounded by a special ops military unit and ordered to stay indoors.
Single-mother Beth is forced to spend more time with Kieran, a one-night-stand she drunkenly picked up the night before.
When there is no official explanation over what's happening, Beth becomes increasingly concerned over the whereabouts of her estranged daughter Jodie who went missing after they had a fight.
Suspicions are aroused that the event has something to do with a container ship that shed its load on a nearby beach... something savage has escaped.
More frightened for her daughter's safety than ever, Beth mounts increasingly desperate attempts to rescue Jodie from the unknown danger within.
