年輕時懷抱歌手夢的哲太（寺尾聰飾演），為了家庭與兒子雄太（松坂桃李飾演），選擇放下夢想，在橫須賀經營樂器行，並偶爾登台一展歌喉，過過歌癮。他樂觀幽默、熱愛音樂，是街坊鄰里最熟悉也最受喜愛的存在。然而某天開始，哲太開始頻頻忘記事情，從小事錯亂到回不了家，最終被診斷罹患阿茲海默症。當記憶如潮水般退去，他甚至連摯愛的家人也逐漸陌生。然而不曾褪色的，是他對音樂的熱愛。每當唱起最愛的老歌，哲太彷彿又變回那個神采飛揚的父親，短暫回到雄太眼前。看著父親與病魔對抗的身影，雄太決定用音樂守護父親的笑容與尊嚴。那些一唱再唱的旋律，不僅成為父子倆穿越記憶迷霧的橋樑，也讓哲太年輕時未竟的夢想，在人生暮年悄然綻放…。一段關於親情、記憶與旋律的動人旅程，即將溫暖開唱。
