<P> In a secluded area, away from civilization, James Hoyt and Kristen McKay arrive at night to James' childhood remote summer home . After being tired and irritable after a long evening at a friend's wedding reception, James calls his friend Mike and asks him to pick him up in the morning . Shortly after 4: 00 AM, there is a loud knock at the door . A young blonde woman, whose face is hidden under the shadows, asks "Is Tamara home?" but is turned away by James . He goes for a drive to purchase a pack of cigarettes; before he departs, he starts a fire in the hearth . 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 smoke alarm when she is startled by another knock at the door; she drops the alarm on the floor, unnerved . She calls James' cellphone from the landline, but their call is cut short . She returns to the kitchen, where, unbeknownst to her, a man--Man in Mask--watches her from an adjacent hallway . </P> <P> Kristen notices the smoke alarm she left on the floor is now sitting on a chair, and realizes someone else 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 Man in Mask, staring at her . Screaming, she stumbles into the hallway, and watches as the front door unlatches with a crack . When she goes to push the door closed, the blonde woman, now in a doll mask--Dollface--peeks in a creepy manner . After locking the door, Kristen hides in the bedroom and hears the strangers outside banging violently against the walls of the house . The noise eventually stops and James returns to the home . After she explains what has happened, he goes outside to the car to get his phone, whereupon he finds the car ransacked and sees Dollface watching him from afar . The couple attempt to leave in James' car but another woman in a pin - up girl mask--Pin - Up Girl--rear - ends them with a truck, forcing them to flee . </P> <P> Back inside the house, Kristen and James find a shotgun and wait for the intruders in a bedroom . Mike arrives and realizes something is wrong after seeing the smashed car in the driveway . He enters the house, and James, mistaking him for one of the strangers, shoots him dead . Devastated, James remembers an old radio transmitter in the backyard shed . He leaves and encounters Pin - Up Girl, searching the backyard with a flashlight . When James tries to shoot her, the Man in Mask knocks him unconscious, discharging the gun in the process . Kristen hears the shot and runs to the shed . She finds the radio, but Pin - Up Girl smashes it with an axe . Kristen rushes back to the house where she encounters Dollface, who taunts her with a knife, saying, "You're gonna die ." She tries to leave but is incapacitated by the Man in Mask . Finding themselves tied to chairs in the living room with the strangers standing before them, Kristen demands, "Why are you doing this?" Dollface replies, "Because you were home ." </P> <P> The strangers then unmask themselves to the couple offscreen and take turns stabbing the couple before leaving the home . As they drive away in the truck, they come across two young boys on bicycles distributing religious tracts door - to - door . Dollface comes out of the truck and asks if she can have one of their tract cards . One of the boys asks her, "Are you a sinner?", to which Dollface responds saying, "Sometimes ." The boy gives her one, and the strangers drive away as Pin - Up Girl states, "It'll be easier next time ." The two boys come upon the house and discover the chaotic scene with a messy house, including blood on the walls, a gun sitting on the kitchen counter, an empty wedding ring box, a bloody knife, red rose petals on the floor, chairs and tables tipped over, the record player still playing but no songs or music, and the bloodied bodies of Kristen, James, and Mike inside . One of the boys approaches Kristen's body and attempts to touch it . As he reaches out to her, Kristen wakes, startles him by grabbing his hand and screams . </P>
