[ The Unsaid]( Psychiatrist Michael Hunter (Andy Garcia) and his wife are watching their daughter Shelly's school play. Their son Kyle, who is suffering from depression, stays at home, because he can not stand being among people as he says. While the parents are applauding Shelly, Kyle commits suicide in family's garage.

Several years later the family has fallen apart because of their loss. Michael retreats, writes books, holds speeches for University students, but he no longer treats patients. When his former student Barbara Wagner approaches him asking for help with a case he initially refuses, but then gives in to taking over the case of 17-year-old Thomas "Tommy" Caffey (Vincent Kartheiser), who had had to watch his father murder his mother. It is Michael's job to decide if the teenager can leave the psychiatric facility when he turns 18. But while working with Tommy, Michael realizes how much the boy reminds him of his own son Kyle and feelings of guilt arise in the psychologist.

In flashbacks and conversations the viewer receives background information of Kyle's suicide. Michael had had his son see a therapist, an old university friend, Harry Quinlan, instead of taking medication. In his son's suicide letter Michael finds out that Kyle was sexually abused by Quinlan. When Michael wants to confront Quinlan, he doesn't answer the door. From the back door, Michael then sees how Quinlan holds a gun to his own head and commits suicide, while Michael angrily yells at him to shoot himself.

Tommy kills a girl at a party because she wanted to have sex with him. At the same party Tommy befriends Shelly and they get closer. Shelly tells Tommy about Kyle. From then on Tommy uses the information in therapy sessions and manipulates Michael, who more and more sees his own son in him.

When Michael visits Tommy's father in prison he finds out that Tommy's mother misused him as a lover and slept with him regularly, the reason why the father, who came home early one day, bludgeoned the mother to death.)
