Laura, a young journalist living an isolated life in a cramped Mexico City flat, is not lucky in love. The banality of her daily life stands in stark contrast to her nightly pursuit of sex and love. These short-lived affairs barely take the edge off her isolation, but then she meets the brooding, would-be actor Arturo. Their chemistry ignites feelings in Laura that leave her deeply troubled. The two embark on an increasingly dangerous sadomasochistic relationship in which pleasure, pain and love merge. Their physical relationship seems headed for a very dark place as her secret past resurfaces, pushing Arturo to the limit in this intense, powerful and at times deeply unsettling movie.
