Pink Floyd (in this movie, one person) has had nothing short of a hard life. His father died seven months before his birth, in World War II, prompting the poor baby to be overprotected by his mother until his venture away from the home. This leads him to build a mental wall to isolate himself from the world and protect him from being hurt. He becomes a rock star, but totally ignores his wife. After his wife cheats on him, Pink blames her, goes crazy on a groupie, and finishes the wall. However, he learns too late that isolation is not the answer.
