Knock knock

A group of high-school friends go on a trip for their school project.
The project talks about old/ancient houses, what happened to it, and what's the house story.
After going for several times to that house, the teenagers saw that things started to change, in the house and theirselves.
Things escalated to the worse and they started to shatter.
Memories lost, Break-up's, Tears, Hatred, love and betrayal.
What's the house story?!Will they be able to make it out?! What will happen in there?! Will they all survive?!
