Lewis seems like a typical guy living an ordinary life. You would never guess that he's been plotting revenge on a lady named Cathy for several months. One day Lewis decides to grab Cathy in the middle of the day with no attempt at being subtle. He brings her back to his home, where he locks her in a room built of four cement walls where no one will be able to hear her screams. His plan is to get her to turn herself in for the evil secret act that he knows she did in her past.
