All hell broke loose in those four days… The city of Karbala, in 2004, during the Iraq War. Ashura, an important Muslim holiday, is about to begin, when Al-Qaeda and As-Sadra militants attack the City Hall, headquarters of the local authorities and police, where arrested terrorists are held. Furious attacks are repelled by eighty Polish and Bulgarian soldiers, equipped with weapons and rations to last for only 24 hours. They lose communication with their base, and do not know when to expect support. On limited rations of food and water, using almost all of their ammunition, they kill over 100 enemies, without a single loss, thus winning the biggest Polish battle since World War 2.
