五年級的暑假，Hana計劃一次全家旅行，意圖挽回面臨破裂的家庭關係，憧憬能返回她年幼時家庭旅行照片中的快樂時光，可惜事與願違。一天，Hana遇上十一歲的Yoomi和她七歲的妹妹Yoojin。她們的父母經常出外工作，兩姊妺暑假暫託在她們狹小的閣樓中。兩姊妹面臨業主逼遷，Hana決定出手相助。三個小姐妹無助中互相安慰扶持，更決心要保衛她們自己的家園。但憑她們微小的力量，能否挽救失落的家園？繼第一部長片《我們倆》(第13屆)大獲好評，允佳恩再次由小孩角度出發，登門入屋探索家庭和成長的主題。

With her parents’ marriage on the brink of collapse, precarious 12-year-old Hana tries to put together a family trip she thinks will solve everyone’s problems. In turn, she finds solace by becoming the de facto big sister to two girls whose parents are away for work. In the highly anticipated follow-up to her critically acclaimed debut The World of Us, writer-director Yoon Ga-eun once again offers delicate insights of the inner lives of young girls facing adult issues spinning beyond their control. Gentle, melancholic and heartrending, this coming-of-age drama firmly places Yoon as one of the best up-and-coming filmmakers in Korea today.
