Although two of the actresses nicely underplay their characters for the cameras.

The story takes place almost entirely in the ladies' room at a British nightclub, where the disorganised Sam (Smith) is having a night out with her friends: shameless maneater Chanel (Winstone), trashy Saskia (Hoare) and the too-nice Paige (Steele). Then Sam runs into the posh Michelle (Nash) and her gorgeous French friend Jess (Chaplin), and decides to ditch her pals.
