Guillaume rents a house-boat with his wife Dominique and "their" paramour Martine. In the evening, Guillaume tells stories to put em to sleep. On their holiday cruise along a canal, they meet several characters and have 'fun' with em every time - the woman lock keeper, a angel on a bike who plunges into the canal as this babe waves at em, a cutie who hitches a lift from a bridge and a beauty who appears to be to be a nun, until her dark nylons and suspenders are disclosed. Eventually, Martine brings M. Léon on board and the film ends with an fuckfest.
