Alter Ego讲了什么？

Joseph Batista, a taciturn yet deeply humanistic police officer, has returned to Marseille after thirty years of a brilliant career in Paris. He has a good reason for coming back: he has just discovered that he has a daughter and a grandson he has never met. Lyna, who has become an investigating magistrate, is determined to make him pay for his absence. Meanwhile, Samy Kaddourian, a brilliant but disorganized lawyer carrying an enormous mental load as a single father raising three children, defends the very suspects Batista is trying to put behind bars. This hypersensitive, clingy attorney and this police officer who is too proud to show his emotions keep crossing paths on criminal cases, each on opposite sides but both fighting to uphold justice. As they get to know one another, they argue, clash, and gradually grow fond of each other—until they realize they may have found their perfect counterpart.
