A vivid portrait of the pressures and insecurities faced by young women.

Powder Room – a comedy with an all female cast and set in the private space of a female public toilet- follows a group of women on a night out in a London club.

Sam (Sheridan Smith) is there with glamorous ex-college friend Michelle (Kate Nash), who is over on a short visit from Paris with her fashion blogger business partner Jess (Oona Chaplin).

Michelle earns lots of money and has recently got engaged.  And although they have not seen each other for five years, Sam has been following her every move on Facebook.

Feeling inadequate, Sam brags about her job as a lawyer and her boyfriend Sean, but it soon becomes clear that they split up over a year ago and the best job Sam ever had was working in a cafe.

And to make matters worse, someone has spilled red wine over the back of her jeans.

By chance Sam’s best friends, sassy Chanelle (Jamie Winstone), hedonistic Saskia (Sarah Hoare) and dependable Paige (Riann Steele) are also in the club.

And despite her best attempts to maintain the facade, Sam’s cover is ultimately blown. But she also discovers (rather too predictably) that her friends’ Parisian lifestyles are not quite what they were first cracked up to be either.

Powder Room is based on Rachel Hirons’ play When Women Wee, and is the debut feature of director Morgan Jane (MJ) Delaney who was behind the You Tube hit Newport State of Mind, a spoof of the Jay Z and Alicia Keys hit about New York.

Although some of the characters draw a little too heavily on well-worn female stereotypes – the sensible one, the sluttish one, the glamorous one and so on – there is much in this film that women will recognise from the underage clubbers who haven’t quite learned to read the signs of human attraction to the bouncer who has seen it all before.

As a new survey of young women in Britain reveals nearly half feel they have no-one to turn to and two thirds say they have been discriminated against at work this film is a vivid portrait of the pressures and insecurities they face.

Powder Room will be in UK cinemas from 6 December.
