The subject of this film, which takes an analytical look at the life of all of us with an analytical eye, is the evil microbe that has slowly infiltrated the organism of the Czech nation. Through the intertwining fates of three couples, it evokes domestic life before November 1989, burdened by a suffocating atmosphere of unfreedom, and after November, when relatively nothing has changed because people have not changed. The bleak conclusion suggests that the plague epidemic is still ongoing.
