Two years after Stanley Kubrick's death, Jon Ronson was invited to the director's estate to explore the hundreds of boxes the legendary film director had collected. His estate in Childwick Bury, near St Albans, was filled with boxes containing a carefully filed archive gathered up during Kubrick's life: including scripts, research, correspondence, costumes, props, models, production schedules, photography, books and film equipment. This film follows Ronson's journey through Kubrick's boxes, as he seeks to understand the enigmatic director through the many things he acquired in his life, and then left behind.
