Shirley Valentine is a one-character play by Willy Russell. Taking the form of a monologue by a middle-aged, working class Liverpool housewife, it focuses on her life before and after a transforming holiday abroad.

Wondering what has happened to her youth and feeling stagnant and in a rut, Shirley feels as if her family treats her more like a servant and she finds herself regularly alone and talking to the wall while preparing an evening meal of "chips and egg" for her emotionally distant husband. When her best friend wins a competition for two to Greece, she packs her bags, leaves a note on the cupboard door in the kitchen, and heads for a fortnight of rest and relaxation. In Greece, with just a little effort on her part, she rediscovers everything she had been missing about her existence in England. She finds so much happiness, in fact, that when the vacation is over she decides not to return, ditching her friend at the airport and going back to the hotel where she'd been staying to ask for a job and to live a newly self-confident life in which she is at last true to herself.
