Matsutaro Yasuda, a retired girl's High School Principal who has lost his wife to alcoholism and is forsaken by his Daughter, moves to an old apartment in a country town. Yasuda, at his new address, meets a little five years old girl who lives next door. Sachi, the little girl, clenches on an iron fence at the apartment. All alone, she is gazing into the distance. Angel's wings made of cardboard are on her back. She is barefoot and wears a summer dress in spite of it being winter. On her leg there are scratches and bruises. Yasuda speaks to Sachi but she does not smile or say a word. When night falls, violent voices can be heard from next door to the mother and her lover echoing in Yasuda's room almost every night. Yasuda blocked out his emotions. He didn't want to hear or see anything. However, little by little something moved his emotions we can call it passion. When he looked into the little girl's eyes, which are also lacking in emotion, something seemed to overlap his wounded heart. "Have you ever seen a blue sky? Where clouds appear like cotton candy and a white bird is flying high?" "Would you like to walk with me?" Yasuda and Sachi begin their long walk.... During their walk, the two meet a young boy named Wataru at a small desolate train station. Wataru seems to be easygoing. However, he is also lonely and holds an empty feeling in his heart. The passing Wataru joins the two on their journey but the trip goes in an unexpected direction when one day Sachi begins to open her heart to Yasuda and Wataru. Cardboard Angel wings begin to fly toward a real sky....... 漫步，是这样一种态度。献给永远的少年。心安即是家，无论在人间、地狱还是天堂。。长途漫步，漫步人生。。The reason of living，the reason of death。你！天使！蓝天！。没有目的地的旅行。漫步人生，只为了看见心中蓝蓝的天，蜜糖般的云彩，飞鸟的翅膀。。。。。关于漫步的自絮。如果可以的话，也一起去旅行吧。 松太郎（绪形拳 饰）和家人的关系非常糟糕，也许是他的性格太过刚厉，也许是因为身为校长的他工作太繁忙。松太郎的妻子已经身亡，只剩下一个憎恨他的女儿。现在他已经慢慢老去，孤独的老人决定搬到偏僻之地一个人居住。 在这里，邻居小女孩（杉浦花菜 饰）的遭遇让松太郎唏嘘不已，她有一个风尘的母亲，冷漠的家庭和不温不饱的童年，偶尔在自己寂寞的小世界里自得其乐。松太郎和她成为了朋友，并带她离开这个灰暗的地方。他们一起上路，一起在蓝天白云下散步，开始一串长长的漫无目的的旅程，见证着生命的消长。然而，松太郎却作为一个拐带女童的老头，最终被带入监狱，松太郎和小女孩不得不分离，却在人生中留下了长途漫步的心灵财富。
