Crushed by a messy unrequited love, a young queer poet, through the confidence of their best friend and the truth of their art, finally reckons with their own emotional baggage (or, 'boulder'). The film oscillates between 16mm narrative compositions of everyday life and Super 8 montages which imagine the world of their poetry.
26岁主人公·田中直子（永野芽郁 饰）原本过着普通的白领生活，但公司聘用一位魅力无边的不良女白领兰（广濑爱丽丝 饰），中途入职的她和直子产生友情，二人会一起去咖啡店，但其实她是以「丝卡将」（和风图案夹克）为标记的人气不良OL。直子被卷入地狱般的派系斗争，能否重获平稳的OL生活？
