The lawyer Dr. Wagner is a real disgust - neither for his employees nor for the residents of his apartment building does he have a friendly word. But when a violent pipe break in Wagner's penthouse flooded the apartments underneath on Christmas, the neighbors who had become "homeless" made a radical decision: Since Wagner refused to help his tenants, they settled under the leadership of the resolute Rita and her adult daughter Sophia without further ado with the stubborn loner - for a few happy, if not exactly quiet, Christmas holidays.
Unfortunately the movie Oh Tannenbaum is not yet available on HBO Max.
