The desire for freedom in Communist Czechoslovakia led to the formation of a group of individuals who professed an inclination towards the principles of the underground movement. They became outsiders by their own choice, so that they could live freely. Today, they live predominantly in the past, unable to overcome suspicions of betrayal in the form of cooperation with the secret police. Throughout their story drifts the spirit of their tragically departed guru. In an effort to come to terms with the past, an old companion organizes a revival concert. Will these freethinkers reach a truce?
