A strait-laced French student moves into an apartment in Barcelona with a cast of six other characters from all over Europe. Together, they speak the international language of love and friendship.

Five years after their summer together in Barcelona, Xavier, William, Wendy, Martine and Isabelle reunite.

Xavier is a 40-year-old father of two who still finds life very complicated. When the mother of his children moves to New York, he can't bear them growing up far away from him and so he decides to move there as well.
