在这部你不是犯人吧？剧情/犯罪片中,森田樱（贯地谷诗穗梨 饰）从小就热爱阅读推理小说，立志长大之后成为一名推理小说家。而她的确也是这方面的人才，森田樱拥有着强悍的逻辑思维和强大的记忆力，任何细微的蛛丝马迹都逃不过她的双眼。
某一日，森田樱结识了名为宇田川教生（要润 饰）的新人刑警，教生是含着金汤匙出生的富家大少爷，一眼就看出森田樱是一件了不得的“武器”，于是将森田樱招入麾下，从此两人结为搭档，破获了一桩又一桩的奇案。让森田樱感到头痛的是，教生似乎生来就拥有一种奇怪的魅力，总是会和案件中的女嫌疑人发生暧昧不清的感情，不仅如此，他那仅凭着一时冲动而做出的推理漏洞百出，常常令她啼笑皆非。
Sakura Morita is a peculiar "freeter" (freelance part-timer) who dreams of becoming a mystery novel writer. While switching between various jobs throughout the series, she also becomes an assistant to Officer Kyosei Udagawa, a detective who discovers her excellent memory and reasoning skills. On the other hand, Udagawa, who has just joined the police ranks through his father's connections, is fairly inept and has a tendency to fall in love with female suspects.
