Stella has settled for suburban peace with a pedantic husband, a dissatisfied daughter and a clutch of beloved grandchildren - who all take her presence in their lives for granted. Then Cameron Keene, her boyfriend from her teenage years who'd left for America to become a rock icon of the Sixties, returns to England. Much to Stella's astonishment, Cameron announces in an interview that his most famous song, which became a legendary love anthem across the world, was written about Stella, and that he has come back to find her.
