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.
每天早上,我的母亲总是先于我醒来,她会先准备好我的午餐,然后出门。每天傍晚,我的母亲会在外面吃过晚餐之后才回家,静静地梳洗完毕后就又回到属于她的房间,打开收音机关上房门,在晚上九点睡去。我们生活在相同的空间里,但几十年来,我们就像是同个屋檐下的陌生人,唯一的交集是她为我准备的吃食,我们之间没有嘘寒问暖、没有母女间的心里话、没有“我爱你”。当我注视着她,我知道在那震耳欲聋的沉默之下,藏着让她难以面对、无法言说的秘密。我知道在紧闭的双唇背后,是令她窒息且摆脱不去的耻辱。这天,我终于鼓起勇气与她开启对话,但我真的准备去好面对她将给出的答案了吗?我们又是否都能够好好面对那些已经被埋藏许久的过去?
