Mathieu has everything a young man could want, a great apartment in Monaco that he shares with his best friend Sébastien, plenty of money, and all of the women he could ask for. When Emma, strong-willed and working in Monaco for the summer, is forced to move in with Mathieu, arguments quickly ensue, and it's clear that the two just aren't compatible. Between a battle of the sexes and some of life's great lessons, Emma and Mathieu try to figure out what they want, and what a relationship means to them. And little by little, those disagreements become less and less important.
