You press send, and your message disappears. Full of secrets about your neighbors, it’s meant for your sister. But it doesn’t reach her --- it goes to the entire local community WhatsApp group instead. As rumor spreads like wildfire through the picture-perfect neighborhood, you convince yourself that people will move on, that this quickly will be forgotten. But then you receive the first death threat. The next day, a woman has been murdered. And what’s even more chilling is that she had the same address as you --- 26 Oakpark --- but in a different part of town. Did the killer get the wrong house? It won’t be long before you find out.

Anya is enjoying a relaxing bath when she hears a noise coming from the ceiling. Through the open bathroom door, she sees the attic hatch swing down, and a masked figure drops to the floor. Thirty seconds later, Anya is dead. Across town, Anya's old school friend, Julia, sees an online video of a masked figure climbing out of an attic. She suddenly realizes why the footage is eerily familiar: it was filmed inside her own house in a luxury gated community, designed to keep intruders out. Why would a stranger target Julia? Unless of course, it's not a stranger at all.
