一个教书法的老师说：我能在7天的时间把你带出来。一个纪录片导演说：行，我把这个过程拍下来。于是有了本片。7天，素人，书法家，如何转变？7天能改变什么？本片实践的就是这个问题。

帝丹高中即将为义演排演舞台剧，一向积极的铃木园子自告奋勇担当主演和编剧的任务。她写了一个杀人事件的剧本，准备把自己塑造成推理超强、魅力十足的女主角。故事讲述专横跋扈的新闻周刊社长大下武男独处一室的时候被人杀害，与他素有过节的职员东田直也、南泽淳平、西岐荣子和北野强成为主要嫌疑人。这本是一出悬疑刺激的推理剧，但是园子却始终不能为剧中关键的线索找到合理解释，创作顿时遭遇瓶颈。她求助小兰和少年侦探团的伙伴们，大家七嘴八舌，怪点子频出，甚至外星人的情节都被引入进来，然而没有一个令人满意。无计可施之际，他们给新一打电话求助。柯南最终能否给出一个合理、完美的解释呢？

Byeong-tae (Yoon Mun-seob), a philosophy major at Y University, goes to a group blind date and meets Young-ja (Lee Young-ok), who studies French literature at H University. The young men and women of the 1970s, who have grown up under the influence of a rapid influx of Western culture, agonize over college issues, family conflicts, and their future paths in life. But such struggles are self-derisive, and they can see no tomorrow waiting for them. Between Byeong-tae and Young-ja, there is no promise of love, of any kind. They simply meet, and exchange meaningless conversation. Meanwhile, Yeong-cheol (Ha Jae-young), who always rides a bike and declares every time he drinks that he will set off in search of a whale, has feelings for another girl he met on the blind date, named Sun-ja (Kim Young-suk). But Sun-ja rejects Yeong-cheol, who stammers, has no prospects, and was even turned down for military duty due to health reasons, and he falls into despair. With nothing to look forward to, Byeong-tae and Yeong-cheol head to the sea. Yeong-cheol, who boasted that he would catch a beautiful whale in the East Sea, commits suicide, and Byeong-tae enlists with the military. Young-ja comes to see him off, even though she said she wouldn't see him any more, and the two of them kiss through the open window of the train that will carry Byeong-tae away.
