Mikołaj na sygnale.

Paramedics from Leśna Góra are getting ready for Christmas! When Dr. Góra tries to prove to his son that Santa Claus exists - it ends with the intervention of firefighters. When Wiktor, together with Czarek, hangs Christmas decorations in the house, a violent dispute ensues. Lisicki is also extremely unlucky, and is met with unpleasant events. His sister Wanda, on the other hand, plans an intimate evening with Ben, but her plans will be effectively thwarted. On the other hand, a special guest turns up at the Lisickis' house: uncle Leon from America, as eccentric as he is rich!
