四個重金搖滾邊緣人，主唱是療養院清潔員，吉他手是馴鹿屠夫，貝斯手是圖書館管理員，聽歌過耳不忘，曾死過兩次的鼓手最有衝勁，一心想出國演出；他們在地下室練團12年，從沒上台表演，鎮上幾乎每個人都鄙視他們，披頭散髮被人譏笑是「娘炮」，騎腳踏車還會莫名被臨檢，他們只好把所有怒 氣都發洩在音樂上。 有天，城裡來了一位國際出名的重金屬音樂祭主辦人，意外獲得演出消息的他們，不管三七二十一，決定以團名「插爆直腸」出征上路，一路橫衝直撞，偷車、盜墓、渡海、挾持精神病患樣樣來，甚至闖越兩國邊境與武裝軍人對抗，費盡千辛萬苦，只為了一戰成名的演出機會…...

Zilan, a young woman, returns to her home town looking for traces of her dead brother, killed by ISIS. But her town is not what it used to be: social and political tensions have escalated into a state of war. The people have risen up to demand their political autonomy and the police and army repress them with brutal force. But the city’s resistance will go on for more than 100 days and Zilan will not remain a passive witness. Based on the diaries of those who died fighting and the testimony of survivors, who are the protagonists of the film, Çelik's first feature explores concepts such as hope, friendship, sacrifice and loss in the struggle for freedom of a group of young people.
