Margaux is a 25-year-old, living a carefree but unsatisfying life punctuated by frequent one-night stands. She can't help herself. One night at a party, she meets another Margaux, 20 years her elder. Troubling details and similarities seem to link the two women--starting with the 6:57 AM train that they are both taking to Lyon the next morning. On the train, Margaux (45) bumps into Marc, her still-very-handsome ex, whose charm inevitable resonates with Margaux (25) as well. Soon both women will find it increasingly difficult to let go of one another as well as let go of Marc--the both of them. What is it like to meet your own self? Margaux and Margaux will find out.—Happy_Evil_Dude
