The movie is to combine a film noir-style investigation with an exploration of altered states of consciousness, focusing on the story of 50-year-old Otto Ganz, the owner of a thriving building and civil engineering company that operates worldwide. One day he has to travel to North Africa to deal with some urgent issues and there, Ganz is confronted with memories of his youth, which he had tried to forget for many years.
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.
