It could happen to you. 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.

Even in a wealthy neighbourhood like this. 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 in a luxury gated community, designed to keep intruders out.

Even with friends like these. Why would a stranger target Julia? Unless of course, it's not a stranger at all.
