Dag Vag was formed in the late 1970s. It all began when frontman Stig Vig was given a guitar to play in his prison cell, and before long, the band took Sweden by storm. The members themselves described their music as "transcontinental rock-reggae," and they produced hits such as "Dimma," "Musik," and "Rulla på." Stig Vig passed away in 2012 following a long illness. This film traces the band's journey from start to finish through unique footage and clips from a bygone era. Friends and colleagues share their insights into the band's significance and musical evolution—including their legendary tour with Ebba Grön—featuring appearances by Joakim Thåström, the band members, and others.
