The waitress Gita from the hotel "Bobí vrch" approaches her lover who has not left his wife yet and gives him an ultimatum: if he does not do all according to her wish, she will announce to the police his machinations with foreign currency.
Set in the early 1930s, a young man finds a job as a dishwasher in a hotel and quickly works his way up the ladder. Loosely based on the novel by Henryk Worcell.
Jealous of her vapidly "good" sister's popularity, poisonous Viktoria doses pretty Klara's tea with a slow-acting fatal substance. As the latter grows hysterically weak, the former finds success increasingly compromised by guilt, blackmail, and the pesky need to kill others lest she be exposed.
