Albert, retired dance teacher, has lost his will to live. Unknowingly falls in the plot of her daughter, and starts therapy with a psychiatrist, with him not realizing. Along the way he finds abusive people, but also his way back to life.

Albert never wants to dance the Slow Waltz again. The Slow Waltz belonged to his wife Martha and him. Albert is a retired dance teacher and has been a widower for three years. He misses his wife so much that he has lost all courage to live, buries himself in his semi-detached house - and meticulously plans his death. But an unforeseen dance class with an exceptionally untalented student thwarts his plans. What he doesn't know is that his daughter Ina has hatched a plot to save him. The untalented student is psychiatrist Hanne, who is supposed to treat Albert unnoticed - as a kind of undercover therapist, so to speak. And the plan actually works: Albert realizes that he is still needed and that there is a lot that makes life worth living - not least Hanne, who is as stuck in the past as he is. But then Albert has to find out in (self-)righteous anger: There are unscrupulous people who shamelessly abuse his trust - like Ina or Hanne.—ADR Das Erste
