Movie about asylum?
 

I recently saw a movie which was set in an abandoned insane asylum and i was wondering if anyone knows the title. In this a few contractors were hired to reconstrust the asylum or something of the sort. One of the guys ends up having ties to the asylum in some way and another kills the rest of the workers in the end or something of that nature. If you know the title please post it it would help me alot..

Sounds like Session 9.

It is Session 9..no doubt about it

that one was easy
