Inspired by Kobo Abe's novel The Box Man, Confessions of a Box Man tells the story of Thomas Zielinski: a sexually frustrated journalist researching a group of men who leave society behind for life inside a cardboard box. Mistaken for common street trash, the Box Men move about almost invisibly, wearing only boxes, rubber boots, and looking at the world through small eye-like slits. After landing an interview with a former Box Man, the first of its kind, Thomas learns about their obsessions with women’s legs, which they see as objects of erotic worship. Seduced by the Box Man’s strange tales and challenged by new urges that he can’t repress, Thomas fails to escape an impending downward spiral, which threatens his family, career, and sanity, events mirrored in the film by a series of micro-documentaries that interrupt and comment on the Box Men. Subjects include the power of the Box Man’s gaze, the history of the box in western art, legs and ankle contests, and an origin story focused on Catholic priests who first entered confessional boxes. By mixing fiction and reality, Confessions of a Box Man presents an imaginative world where perverse forms of male desire can only lead to tragedy or transformation.
