The most widely associated perception of Straight Edge involves abstinence from alcohol, tobacco, other drugs and promiscuous sex. Since it's origin in the early 1980's these beliefs have spread all over the world, connected through the Punk and Hardcore music scenes. Through interviews with musicians that directly shaped the idea of Straight Edge from its inception until today, EDGE reveals that the abstinence from drugs was established as a youth counter culture rejecting a society dominated by substance abuse and hegemony. Ian MacKaye (Minor Threat, Fugazi), Ray Cappo (Youth of Today, Shelter) and Karl Buechner (Earth Crisis, Freya) give witness to their perception of the history of Straight Edge, why it was so important to them and what it changed in their personal and professional careers. But they also address problems like violence, sexism and intolerance that emerged within Straight Edge, and how it changed the 'scene' as well as its public image.
