When a woman rents a miserably tiny room, she finds mountains of belongings from the previous tenant, "Anthony," as well as messages on the machine from the landlord, his mother, and a calm, threatening Irishman. As she cleans up the place, she begins to experience uncanny visions, nightmares, and the feeling that Anthony is much closer than she imagined. "Sugar" is a terrifying, intoxicating cockroach-eye view into the sweet surrender of hysteria and comforts of urban claustrophobia that will have you crawling out of your skin.
