The Hairdresser's (2012)

This hair salon is at the heart of these women's lives. This is THE place where they can tell all their little secrets, their hopes, their desires. it is also the place where they discover each others' infidelities. The boss of this salon gets fucked in the ass by her lover, whose wife is also fucking the boss' husband. Everybody cheats on everyone and every "hello, how are you" is so hypocritical.
