在这部流浪的狗纪录片片中,流浪的人生，流浪的狗......曾紀錄過宜蘭傀儡戲、學校併校消逝等主題的導演林英作，此次跟著台語教師林錦賢的背影，與他一起驀然回首歡唱相褒歌的日子。
Taunted in primary school for not being able to speak Mandarin, Lin grew up to become a teacher of the Taiwanese language and a scholar of regional cultural history. His fate of a substitute teacher is that of a drifter, and his in-depth research in cultural history no longer has practical application. Lin looks back on his life and realizes that he is like a stray dog with no future.
