Four Windows (2006)

Divided into four chapters - Son, Daughter, Father and Mother - "Four Windows" is a look inside the brains of a not-so-normal German family. Son leaves for school but actually cruises the local gay video arcade. Dad hires a hooker, Mom flirts with the handyman and Daughter rides the subways, looking to share some intimate moments. At dinner that night, the secrets they hold come to a head.
