Five friends in one mansion , it's a weekend midnight sleepover and nothing seems suspicious this group of friends enjoy as they tell their deepest secrets , play silly games and talk about their future plans, we get a chance to know all five characters - who they are and what they like , But what happens when who they are and what they like starts to haunt them? one friend goes missing

trumpeting lightening and the awakening showers of the rain hits the moist ground, only to hear three continuous sketchy sounds escape at the door knock knock knock

Do you open ?
