Geraldine and Reg, ageing hippies now trapped in Green Belt respectability by Geraldine's domineering mother, Mrs Carmichael, are giving a dinner-party. Geraldine decides to liven up the evening a bit by impersonating Reg's imaginary brother Rollo, a cad and a bounder. When Reg retaliates by dressing up as Rollo's eccentric wife, Lillian, chaos ensues. Olwen Wymark's suburban comedy is a rebel's fantasy, a hostess's nightmare, and a hijinks treat for its audiences.
