A car crash in Mexico City links together the lives of three people-a young man obsessed with his brother's wife and a fighting dog; a model, scarred and crippled by the accident, whose beloved Lhasa Apso is trapped under her apartment floor; and a scruffy hit man who lives with a pack of wild canines-in director Alejandro González Iñárritu's acclaimed crime drama. Vanessa Bauche, Gael Garcia Bernal, Emilio Echevarria, Goya Toledo star.
