Well ok.. but too bad.. woulda been a great movie. It was released in 2003: spoilers below
THe ppl that imprisoned the man is the CEO of some big name corporation. WHat happened was that back when they were in highschooll, the dude who gets imprisoned witnessed the kid (who would later become the CEO) have sex with his sister. He tells his friend who tells everyone and eventually everyone thinks his sisters a slut and the girl gets all emotionally shattered and commits suicide. THe brother later grows up and kidnaps the dude and imprisons him for 15yrs. Why? Because the dude who gets kidnapped, his daughter, is like 3-4 and in 15 ys she will be 18 -19 (cant remember) the exact age that his sister was when she commited suicide due to the rumor, back in the day. Well, using hypnosis he also kidnaps the dudes daughter , makes the guy and his daughter think they are complete strangers, make them encounter each other , and fall in love. And I really do not want to get into anymore details because , well it gets really fucked up from that point on. THe plot follows the guy going around beating up ppl with a hammer once he was released from his prison,as he tries to find out whats going on. One of the best parts is when he yanks out all of this guys' teeth with the hammer as revenge. Now go watch it and stop ruining amazing movies for yourself.
