Hi,

Me and my friend are trying to find the name of an horror movie

Its an horror movie with torture scenes (?)

She said its about an abandoned girl(on a lake? Not sure) that later becomed a hooker/whore

That girl started to work as a hooker on a house and then strange things started to happen

Her head/face has a evil spirit/part of her sister that does all the evil stuff in the movie but no one trust on her (not sure too)
