In 1981 in the troubled Poland, when the father of the medical student Wietold Dlugosz dies, he asks one year leave to the dean of the university to rethink his vocation to medicine. He decides to travel to Warsaw, but while running after the train in the station, three possible events happen. In the first possibility, Witek reaches the train, meets his former sweetheart Czuszka that belongs to an Anti-Communist underground movement and joins the Party after saving hostages of protesters in a building. In the second possibility, Witek is caught by a guard in the station while running to catch the train and reacts, being sent to the court and sentenced to thirty days of community work. He joins the group of students that are against the system, publishing papers in an underground press. While his comrades are arrested by the government agents, Witek is having a love affair with the sister of a childhood friend and escapes from prison; however, his former companions believe he is a traitor. On the third possibility, Witek does not reach the train and decides to return to the university and conclude the medicine course. He marries his girlfriend Olga and they graduate in the medical school. They become successful doctors and Witek accepts to travel to Paris to present the lecture of the dean, who was disgraced with the Party when his son was arrested in a movement against the government. The three serendipities do not bring happiness to Witek.—Claudio Carvalho, Rio de Janeiro, Brazil
