The film is about the early years of famed children’s author Astrid Lindgren (Pippi Longstocking) when she experienced something that was a “combination of both miracle and calamity that came to shape her entire life.”
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.
