Al (Denis Lawson) and Davina Jackson (Joanna Lumley) seem to have the perfect life. At 60, they both look great, enjoy their work (he's a music writer for a newspaper; she works in an art gallery) and having finally said au revoir to their son, are ready to indulge themselves with a funky central London apartment and a retro 70s Silver Shadow Rolls Royce.

Still, something, somewhere, somehow doesn't feel quite right. Is it that their 30-year-old son Orlando refuses to acknowledge adulthood? Or that Davina's sister Veronica and her husband Roger intimidate them with their confident grasp of life and comprehensive pension plans? And don't forget the sexual temptation, the professional jealousy and that burning question: is this the life I wanted?
