When wealthy, recently-widowed suburban housewife, Margery (PENELOPE KEITH), and her 'rough diamond' of a cleaner, Gladys (JUNE BROWN), disturb a house burglar, they knock him unconscious, panic and leave him for dead, fleeing in the cleaner's wrecked old car. What follows is a comedy of misunderstandings in which these two very different, mature ladies are led on an unfortunate series of incidents which snowballs into a crime spree. They prove to be more than a match for the unlikely pair of policemen, DI Woolley (Roger Lloyd Pack) and DS Stringer (Martin Freeman), who are left to solve the ladies disappearance and puzzling string of crimes which follow. As the police net tightens around them, the two very different, mature ladies are propelled on a shared voyage of self-discovery as skeletons fall from the closets forcing both women to reflect on their past lives.
