During dinner, someone fires crossbow bolts by the window, wounding Drake and murdering Tariq. The survivors discovered that their cellular phone reception were jammed. Aimee jogs outside to ask for help but then runs into the garrote wire that slices her throat that kills her. The intruder wearing the fox mask that kills Aubrey, sending off the words “you are next” using blood over the wall.
Then Erin texted 911 and looked for the weapons. Another attacker wearing a tiger mask attacked her, but then she escaped by stabbing the hand. Kelly discovered Fox Mask, panicking and flees the abode, only to be murdered by the attacker that wears the lamb mask. Crispian left the house to search for help. Then Tiger Mask attacked Erin with the axe but she killed him.
Paul locates for the sleeping bags and the food wrappers which indicated the killers had been staying inside the house for quite some time. Then Fox Mask killed him. It is revealed then that Zee and Felix hired the assassins in killing the family so that they could gather their inheritance. Then, Lamb Mask locates Tiger Mask’s dead body and then flips the feast table over in the rage. He discovered the wounded Drake hiding, and then retreats after Erin stabbed him by using the screwdriver. Erin is setting up the nail traps by a house’s entrances, elucidating to Zee that Erin grew up in the survivalist compound wherein she discovered survival skills and combat and Felix kills Drake.
This movie does not reinvent anything; however, it confidently and consistently kept a formula well oiled, then proved to be one from the best films of its kind. The setup has been standard, the big old state house in the forest, the entire bunch of dislikable and likable people, and also some of the outside attacker about to unleash the hell with everybody in the house. Appetizingly, this is not one roll call of the pretty teenagers being slashed and stalked, this is one assorted bunch, old and young, all sizes and shapes and the family bickering that preceded the carnage is one smart move, because the moment that the members of the family started being killed there is the genuine sense of regret and grief coursing through those that yet to be diced and sliced.
