The song centres on the main character, Pink, who having lived a life filled with emotional trauma and substance abuse has reached a critical psychological break. "The Trial" is the fulcrum on which Pink's mental state balances. In the song, Pink is charged with "showing feelings of an almost human nature." This means that Pink has committed a crime against himself by actually attempting to interact with his fellow human beings, defying the mission towards self-isolation that defined much of his life. Through the course of the song, he is confronted by the primary influences of his life (who have been introduced over the course of the album): an abusive schoolmaster, his wife, and his overprotective mother; in the animated sequence, they are depicted as grotesque caricatures. Pink's subconscious struggle for sanity is overseen by a new character, "The Judge." In "Pink Floyd -- The Wall" and the concert animations, the Judge is a giant worm for most of the song until his verse, at which point he transforms into a giant anthropomorphic body from the waist-down (bigger than the marching hammers in "Waiting for the Worms"), his face constructed from various elements of the buttocks and genitals. A prosecutor conducts the early portions, which consist of the antagonists explaining their actions, intercut with Pink's refrains, "Crazy/Toys in the attic, I am crazy,/Truly gone fishing" and "Crazy/Over the rainbow, I am crazy,/Bars in the window." The culmination of the trial is the judge's sentence for Pink "to be exposed before your peers" whereupon he orders Pink to "Tear down the wall!"
