You're not afraid of being alone in the dark...

Anya is enjoying a relaxing bath when she hears a noise in the roof. Through the open bathroom door, she sees the attic hatch swing open, and a masked figure drops to the floor. Thirty seconds later, Anya is dead.

You're afraid you're not alone.

Across town, Anya's old school friend, Julia, sees an online video of a masked figure climbing out of an attic. She suddenly realises why the footage is eerily familiar: it was filmed inside her house. Inside her house in a luxury gated community, designed to keep intruders out.

And now your worst fears are coming true.

Why would a stranger target Julia? Unless of course, it's not a stranger at all.
