After the suicide of his mother, Patrick is searching for his supposable father.
It’s Dr. Borz‘ sixtieth birthday, which he celebrates at his suburban villa with his family. Borz seems to be the ideal father with his picture-perfect life, for which the fatherless Patrick ached all his life. Patrick introduces himself naturally as the doctor’s son and the family accepts him in their midst. But the doctor's euphoria that he has found his "lost son" will soon disappear.
