James Gibson is an ex-con who has spent his life in and out of prison. One day, his life turns around when he settles down, meets the love of his life and has a child with her, but an unforeseeable tragedy strikes and his life is never the same.
What begins as an annual visit to their family grave-site quickly becomes a night of sheer terror as two brothers are unexpectedly forced to fight back against a sudden onslaught of violent assailants. Soon, eight complete strangers find themselves barricaded inside a rural farmhouse in an attempt to survive against the ever-growing army of murderous creatures outside.
