Sławek Wiśnik, a young, ambitious musician and graduate of the conservatory's organ class, wants to escape from Kaliszewo, a small town near Suwałki, and pursue a career in music. Unfortunately, he does not receive the expected scholarship to study in Heidelberg and has to start a new life in his hometown. His girlfriend, Agnieszka, plans to get married soon, especially since her father, Zenon Nowak, offers Sławek a job running his business. However, this does not suit Sławek, who prefers to play as a substitute organist, and even... as a disco-polo musician.
