Happy 50

To celebrate Yves' 50th birthday, his friends plan to take him to the sunny paradise of Paros in Greece. But due to a flight cancellation, the holiday will take place in a far less popular and much rainier destination: Yves' family home in Brittany. During the vacation, Antoine unveils an unusual gift: a DNA ancestry test for Yves and his family. This supposedly harmless joke has unforeseen consequences, and the friendship of the group is once again put to the test.
