Guillaume rents a house-boat with his wife Dominique and “their” lover Martine. In the evening, Guillaume tells stories to put them to sleep. On their holiday cruise along a canal, they meet several characters and have ‘fun’ with them each time – the woman lock keeper, a girl on a bike who plunges into the canal as she waves at them, a girl who hitches a lift from a bridge and a girl who seems to be a nun, until her black stockings and suspenders are revealed. Eventually, Martine brings M. Léon on board and the film ends with an orgy.
Jerome K. Jerome might have called this Three Sex Maniacs in a Barge.
