白石和彌首次擔任企劃監製
芥川賞入圍作品時隔三十年登大銀幕

烈日炎炎的夏日，整個群馬縣因連日無雨而陷入嚴重乾旱危機，政府為此開始推行一系列限水措施。任職於自來水公司的岩切俊作（生田斗真 飾），每天的工作就是挨家挨戶拜訪拖欠水費的家庭，只要他們不如期繳清水費，就即刻執行停水。某天，岩切和搭檔木田（磯村勇斗 飾）在執行勤務的過程中，遇見了一對小姊妹，她們的父親下落不明多時，本來相依為命的母親有希（門?麥 飾）也突然在某次出門後音訊全無。眼見兩個孩子因為沒有繳費，只能過著無水、無電的艱困生活，看似對工作早已麻木的岩切，內心開始產生了動搖。究竟帶來希望的雨水，能成功降臨在這座日益乾涸的城市嗎？醞釀十年，改編自九0年代同名小說，本片以水為引、藉旱為喻，於銀幕上審視不被年代淘洗的社會議題，包括政策、家庭、社會結構等層次。本片令名導白石和彌跨刀首次擔任企劃製片，邀請生田斗真化身素樸鬱悶的公務員，與門?麥同台，更有宮藤官九郎、尾野真千子力挺演出。
