Angry young women

Duck hurls its audience into the heart of ladette culture with a car explosion offstage, quickly followed by two very drunk teenage girls entering in hyper-short mini-skirts, tottering on their heels with shock at the act of vandalism one of them has committed.

Seconds later, two boys turn up and attempt rape - only to discover their role changing from predators to victims as one of the girls smashes her bottle of Bacardi Breezer, and turns it into a lethal weapon.

Stella Feehily's first fulllength play is, without doubt, an adrenaline rush, a hyperventilating hymn to the age of the angry young woman. Yet while it breathtakingly conveys the sense of lives led in restless escape from smothering boredom, it has to be asked whether it is as much a journey of discovery as it is an emotional rollercoaster ride.

To conclude that despite being galvanising, this play is not particularly revelatory, does not deny the brimming raw promise of Feehily's quick-fire dialogue and her flint-sharp and often fiercely comic characterisation. Director Max Stafford-Clark has lit the trail for two explosive performances from Ruth Negga as Cat ( nicknamed Duck for her large feet), and Elaine Symons as her best-friend Sophie, and the way they use sex and education respectively to escape their parents' world of conversationless marriage and depressing employment prospects.

The most intriguing plot point is Cat's decision to break her relationship with a thuggish boyfriend by having an affair with a writer in his sixties, whose opportunist predatoriness is thinly disguised by his urbanity and love of literature.

It raises serious questions about how a bright, uneducated girl can truly escape a restrictive background - perhaps something to be developed even further in Feehily's next play.
