In this deliciously kinky film that takes place in the wee hours of a Mexico City morning, long-absent Pedro returns to preside over his seriously bent family. But while Pedro is busy making love to his wife, their children Blanca, Teo and Marcos have different ideas about their father's return. Meanwhile, the neighbors are up to their own devices in a wickedly funny and highly charged erotic drama that involves a set of electric trains. This stylish film explores love at its extremes and sex at its most poetically inventive.
