Okay.. so this guy goes to jail or something, but gets to live in a cabin, has a pyschiatrist that he starts getting interested in or w.e.. then during the movie they try telling him all these things and make him think he's crazy (kinda like shutter island) he rips apart the cabin see;s that it is bugged.. eventually escapes.. drives a truck back home and suprises his wife and daughter

I hope I explained it decent.. it has been bothering me for a while
It is NOT secret window. Lol
