Carried out with extraordinary panache, the shocking real story of the struggle to save one of the most holy places in Europe and priceless relics of Christianity. The power of faith and prayers of ordinary people in confrontation with the power of the destructive element. On Monday, April 15, 2019, one week before Easter, dramatic news spreads around the world: Notre-Dame Cathedral in Paris is on fire! Not only Catholics hold their breath watching hundreds of firefighters fight the element. The conditions are extremely difficult, because the fire spreads in the hard-to-reach attic, and the stakes are enormously high, because it is not only about saving one of the most magnificent sacred buildings on Earth, but also priceless relics. The cathedral treasury houses, among other things, Christ's crown of thorns. Time is running out and the situation is becoming more and more dramatic. The roof of the building will soon collapse and bury people and priceless treasures. The commanders of the action consider the necessity of its cancellation when a group of volunteers declares their readiness to undertake the last extremely risky attempt to control the element. Courage, experience and specialized equipment may not be enough to win. Thousands of believers gather around the cathedral to support the heroes with their prayers.
