Le commissariat de police de la petite ville de Richmond a l'habitude de la visite de Margaret Wilberforce, veuve d'un officier de marine, complètement mythomane. Un jour, le digne professeur Marcus loue une chambre à la vieille dame où, tous les soirs, il répète avec ses amis musiciens un menuet de Boccherini. En réalité, ils préparent le hold-up du siècle.
