Edith's dreams of retirement to the sun with her long-term suitor Phil are shattered when her 50-year-old son Roger arrives home, seeking to recapture the happiness of his boyhood.

Phil and Roger make rival attempts to impress Edith on her seventieth birthday. Roger's bright idea is to invite back Mrs Gale, Edith's chaotic former cleaner.

As tensions grow between Roger and Wendy, a midnight break-in brings Edith face to face with a ghost from her past. How can she explain the raffish Bob to Phil?

Bob gives Roger the idea of applying to be a paid carer for Edith. However, Edith is perfectly well, so who can Roger persuade to stand in for her?

Phil is worried that Edith's old flame Bob may be gaining ground and that his own one-time floozy Desiree may put in an unwelcome appearance.
