Michael O’Neil has been incarcerated in an asylum ever since he murdered his mother as a child. His twin brother Sean regularly comes to visit him. Sean now informs Michael that he and his wife Dale are being forced to sell the family home because they need the money. This news greatly upsets Michael. As Sean and Dale go to clean the house up before selling it, Michael breaks out of the asylum. Michael’s psychiatrist Dr Clifford travels to the house to inform Sean and Dale of what has happened. Michael breaks in that night but Sean overcomes him in the basement. Michael is shipped back to the asylum and the others relax. However, once back at the asylum, Clifford does not know whether to believe Michael’s insistent claim that he is Sean and that Michael has taken his place.
