Adventure one sees townie Mirabelle, who has never really had cause to take time to observe nature, experience a series of minor revelations about country life. Experiences that, curiously, she doesn't seem to carry back home into the Parisian episodes. Indeed the first episode feels like a film-apart, largely because it's not referred back to.
The remaining adventures concern how Reinette's fixed ideas cause her headaches in the city. While it's easy to have a set of unwaivering morals and manners living a more solitary life in the country, it's not as easy in 'the big smoke'. Discovering Parisians have a much more fluid moral compass causes Reinette horror and the viewer a degree of amusement. Indeed Episode Two is Rohmer doing, of all things, broad comedy - complete with a Fawlty-esque waiter.
The director also diverts from his well-trodden path with the absence of romance from this movie (accordingly the film storms through the Bechdel test). I also loved the fact there also isn't the shadow of parental influence, the church or a peer group which sometimes operate, with varying degrees of success, in Rohmer's work. The girls really only have each other as a soundboard and that makes the new friendship between these unlikely flatmates all the more engaging.
