The woman is on her laptop looking at more pictures, whilst the man spins basketball. He then puts basketball upstairs, once he walls away from the staircase, the ball bounces back down.

Woman looks at videos of her sister, who is dead, and appears to be stood with another girl who was missing, who she later sees walking past and waves at. Mysterious figure resembles sister. The woman and her little sister had a song they always listened to, which plays in the back. Daytime, a person steps out of car, 'this is the house?'. Couple arguing, then silenced by a loud thump. They both turn their heads towards the doorway. The couple are in bed, there is a figure stood at the doorway. Man looks at a frame, the door creeks open behind him, he thinks its his girlfriend, he looks and nobody is there, he hears footsteps, then the door slams.

He looks up, no one is there. He puts it in a different room, he looks back up and there is a figure. The woman and her sisters song plays whilst woman is washing up. As she changes song, sister is behind her. Man sees woman with another figure in the window. The figure turns and handprints the window. The man runs in, woman is not there, the doors creeks open behind, as someone says his name creepily, the basketball rolls back out, and hits his feet. He picks it up, and sees the sister and woman side by side.

This will start from outside, looking in a window, on a rainy dark night. Mysterious figure stood, behind blinds, then at the top window as the camera zooms out. Piano music sets in as it fades to black and in on the next clip.

A man is out shopping, and bumps into a woman as they both go to grab the same thing. They start chatting and getting to know each other, he asks for her number. The man tells his best friend about her, about how amazing he thinks she is.

A group of friends go to a party, they drink and dance till morning... but what happened during that unbelievably messy night?

The house is trashed. There're beer cans all over the floor, in the garden, on the streets. There is food smeared on the walls, even on the ceiling. People are asleep still on the floors, the couch, all around the house.

Where is the dog? He was there at the start of the night, locked in a room, what happened last night?

The group of friends retraced last night events, can anyone remember what happened?
