While battling his unforgiving childhood and an increasingly rampant depressive paranoia, a middle-aged, broke, and newly single father, struggles to raise his spirited but troubled five-year-old son. William's Lullaby tells the story of Thomas Splinter (Richard Roy Sutton) a widower on the verge of a nervous breakdown in this haunting drama that examines the effects of grief in children and adults alike. Tormented by vivid and prophetic nightmares, Thomas, with the help of a gifted hypnotherapist, is forced to confront a dark secret from his past before it destroys what little is left of his relationship with his son.
