http://www.imdb.com/title/tt1130884/Drama is set in 1954, U.S. Marshal Teddy Daniels is investigating the disappearance of a murderess who escaped from a hospital for the criminally insane and is presumed to be hiding on the remote Shutter Island.
If you all have not seen Shutter Island yet, you need to get it. It's an Excellent movie, I sure did not see the ending coming out like it did. It's 8.1/10 rating on IMDB is well deserved.
