NINE years have passed since Jesse, a writer from the US and Celine, a French working for an environment protection organisation met in Vienna and walked all over the city, talking as if there would be no tomorrow, and then promising to meet again in six months. "Were you there in Vienna, in December?" she asks him. Nine years have passed, and they have met again in Paris. Jesse wrote a novel about their long night together, and at a book signing he looked up, and there she was. As they have only a few hours until his plane leaves, they stroll through Paris, talking about their experiences, views and whether they still love each other, although Jesse is already married with a kid.
