Ο ψυχίατρος Martin Dysart (Richard Burton) διερευνά, τα αίτια που οδήγησαν τον 17χρονο Alan Strang (Peter Firth) καθαριστή στάβλων στο Hampshire, στο να τυφλώσει 6 άλογα. Καθώς όμως ο Dysart ανακαλύπτει τις αλήθειες πίσω από τους δαίμονες του αγοριού, έρχεται αντιμέτωπος με τις δικές του αλήθειες.
Psychiatrist Martin Dysart (Richard Burton) investigates the savage blinding of six horses with a metal spike in a stable in Hampshire, England. The atrocity was committed by an unassuming seventeen-year-old stable boy named Alan Strang (Peter Firth), the only son of an opinionated but inwardly-timid father and a genteel, religious mother. As Dysart exposes the truths behind the boy's demons, he finds himself face-to-face with his own.
