After a terrible accident when their husbands are killed attempting to hold up a security van, for each of the women it is time to stop, take stock and start life afresh. When Dolly finds the plans for the robbery and with the women facing life alone, suppose they were to finish what their husbands started and carry out the robbery themselves?
