Ginny, after breaking up with her boss Philip, goes to his country home to get back some love letters. She tells her new boyfriend Greg that she is going to visit her parents. Greg secretly follows her, and for the rest of the afternoon there are two couples together in Philip’s garden. Greg believes that Philip is Ginny’s father and that Philip’s wife, Sheila, is Ginny’s mother. Philip mistakenly gets the idea that Greg is having an affair with his wife Sheila, and Sheila is led to believe that Ginny is nothing more than her husband’s secretary. But for how long can the real nature of the relationships be disguised? This popular British comedy from 1967 is still considered to be Alan Ayckbourn’s best crafted piece.
