We only saw happiness

Deprived of his parents' love as a child, Antoine is determined to give his son and daughter the perfect childhood he never had. He is a dreamer, an optimist, a man who fell in love at first sight and who believes that he has found the secret to living a happy life. But when tragedy strikes he becomes someone even he does not recognise. Taken to his lowest point, he performs an act of desperation. But can he find a way back? And what does happiness actually mean?
