The twelve-year-olds Jasmine and Jastrip are looking forward to the summer camp organised every year by the ultranationalist Azov Regiment for hundreds of Ukrainian children. During two weeks they will learn how to make the bed perfectly, the benefits of group identity and how to shoot with Kalashnikov. At the same time, the real war is raging in the eastern part of Ukraine. The summer also consists of playing and hanging out with newfound friends, but the goal is to make them proud Ukrainians who are ready to fight and die for their country. Summerwar shows up close how a radicalization process works and leaves no one indifferent.
