In 2007, a message appeared on the Internet that before her death, the clairvoyant Vanga allegedly predicted that in far Siberia, in Bratsk, on March 17, a chlorine plant located right in the center of the city would explode. That "brothers fall asleep and do not wake up." The author of the film specially goes to the city two days before a possible disaster. And he creates a report not about Bratsk and its inhabitants, but about the era, Russia and our contemporaries.
