the mysterious girl walks away. Kristen realizes the chimney flue is closed, and attempts to open it; smoke emanating from the fire triggers a smoke alarm. Kristen attempts to disarm the alarm when she is startled by another knock at the door and drops the alarm on the floor, unnerved. She calls James' cellphone from the landline, but their call is cut short. Kristen returns to the kitchen, where, unbeknownst to her, an intruder watches her, lingering in the adjacent hallway. Kristen notices the smoke alarm she left on the floor is now sitting on a chair, and realizes someone has been in the house. Upon going to retrieve her cell phone from the charger, she finds it is missing and begins to panic. When she hears a noise from the backyard, she arms herself with a knife, and opens the curtains to find the masked man staring at her. Screaming, she stumbles into the hallway and watches as the front door is forced ajar. When she goes to push the door closed, the blonde woman, now in a doll-like mask, peers inside. After locking the door, Kristen retreats to the bedroom, where she hears a loud crash, before James returns. After she explains what has happened, he goes outside to the car to obtain his phone, whereupon he finds the car ransacked and vandalized, and sees the masked blonde woman watching him from afar. The couple attempt to leave in James' car but another masked brunette woman rear-ends them in a pickup truck, forcing them to flee. Back inside the house, Kristen and James find a shotgun and wait for the thugs in a bedroom. Mike arrives and realizes something is wrong after seeing James' vandalized car. He enters the house, and James, mistaking him for one of the intruders, shoots him dead. Devastated, James remembers an old radio transmitter in a barn on the property. He leaves and encounters the brunette woman, searching the backyard with a flashlight. When James tries to shoot her, the masked man ambushes him and knocks him unconscious, inadvertently discharging the rifle. Kristen hears the shot and runs to the barn. She finds the radio, but the brunette woman smashes it with an axe. Kristen rushes back to the house where she encounters the blonde woman, who taunts her with a knife. She tries to escape but is incapacitated by the masked man.
