Once upon a time, music could change the world. 'No Fun' is about that era and a single vinyl record that managed to do it. Featuring a wealth of archive material, the film focuses on the events in Yugoslavia between 1977 and 1980, starting from the debut of the band Pankrti. They acted as a detonator for the local music scene, synchronizing the pop culture of the socialist state with Western movements, breaking out of a closed society, and ultimately changing history. 'Without punk and 'No Fun,' the Berlin Wall would have fallen later!' claims the film's central figure, which also features numerous musicians, journalists, and other key people from the scene at that time.
