After the Islamic Revolution of 1979, the new Iranian regime consolidated its power through the mass removal of opponents: in the 1980s, thousands of political prisoners were secretly tortured and killed. The perpetrators were never prosecuted, and today hold high-ranking government positions. In October 2012, the Iran Tribunal met in The Hague to investigate the executions. This international people's court has no executive power, but aims principally to identify and investigate what went on. For three days, survivors and members of victims' families - including the filmmaker Nima Sarvestani - gave their testimony. The Iran Tribunal was broadcast live. From Sweden, an activist named Iraj follows the tribunal - he is one of the survivors, scarred for life. And along with Mehdi, who works behind the scenes at the tribunal, Iraj dreams of confronting the perpetrators with their crimes. Both men have dedicated their lives entirely to the struggle for justice.
