Mixed with the testimonies of a dozen survivors, most of them young women, terrible scenes retrace from the inside the siege of Mariupol, a large port in southeastern Ukraine on the Sea of Azov, from the start of the Russian invasion on February 24 to the surrender of the last combatants entrenched in the Azovstal metallurgical complex on May 21. According to the Ukrainian authorities' estimate, some 25,000 civilians died during these three months of indiscriminate shelling and firing by the Russian army, which also destroyed almost the entire city of 430,000 inhabitants, which was then surrounded and almost cut off from the world.
