The "poison" in this drama about an unfaithful husband refers to his infatuation with a younger woman in his office, and how this affects his relationships and his own future. Pavel Hnyk (Zdenek Sverak) has been bored with his marriage for awhile and already has a mistress when he first meets Julka (Ivona Krajcovicova), a woman who comes from Slovakia to work in his architectural firm's office. His distraction with the new and physically appealing colleague is detrimental to the renovation project he is working on, and no one encourages him in his romantic adventure. ~ Eleanor Mannikka, Rovi
