The film discusses the growing lack of independence of Japan's youth, who are having a hard time making the transition from the warmth of their parents 'homes into a cold, isolating society, a sluggish economy, and a difficult job market. Many are now reluctant to leave home when they reach adulthood, and instead rely on their parents for room, board, and other material necessities.
影片中講的是日本年輕人越來越難獨立，他們從小在父母的保護下長大，加上社會疏離冷漠、景氣低迷、工作難找壓力又大，種種不利發展，所以在成年後也不想搬離家中，吃、住、用都倚靠父母。
