Two couples of friends who have arranged to meet in the woods get lost and find themselves in an embarrassing situation: the husband of one with the wife of the other? Each couple tries to get through this forced cohabitation honestly, but everything is turned upside down when two young Sunday gangsters appear. What follows is a cross-country chase through the woods, which leads the whole gang back to the house, where one of the couples manages to leave, free at last, on an old tandem, bound for... Africa!
