The Punk Syndrome follows the lives of four band members with developmental disabilities who form a punk-rock band in Finland. The film explores their personal struggles, challenges, and triumphs as they pursue their passion for music.

In December 2016 a remarkable chapter in music history was closed as the Finnish punk rock band Pertti Kurikan Nimipäivät (PKN) retired. Punk Voyage is a feature length documentary film about the last years of the band, with all the ups and downs included. After becoming celebrities in Finland, this incredible quartet continued to conquer new fans around the World. In its seven years run PKN played nearly 300 gigs in 16 countries. In 2015 the band was selected to represent Finland in the Eurovision Song Contest, where they played to over 100 million television spectators. However, the busy traveling and success created a lot of pressure within the band: Kari struggled with the temptations and responsibilities brought by publicity; Sami extended his territory to politics and religion; Toni's and the band's roadie Niila's crush to the the same girl caused conflicts; and Pertti, tired of this all, decided to retire.
