在这部路有多长纪录片片中,導演湯湘竹20年前在人間雜誌上讀到有關台籍兵的報導，得知在台灣也有ㄧ群和他父親具有類似命運的人，一場戰爭將他們全推向遙遠的離家之路。 在山海交際的台東都蘭部落，導演遇到了阿美族青年，也是木雕藝術家的希巨．蘇飛，得知國民黨接收台灣後，一群少年階級被帶往遙遠的中國。導演湯湘竹便以都蘭為起點，聚焦於阿美族，與希巨探訪這些存活下來的台籍老兵。 在尋訪都蘭部落及台東以北僅存的台籍老兵過程中，希巨請示長老的意見，決定在部落的聖地─(都蘭鼻)塑立一座雕像，紀念那些戰死沙場，回不了家的叔叔伯伯們。而後，導演與希巨來到中國，尋訪留在中國的阿美族老兵，這些老兵因為家鄉的異變、生活習慣種種因素，選擇留在中國…… 海有多深、山有多高、路有多長，倏忽十年。前兩個紀錄片的主人翁，我的好友和我的父親，皆已辭世。遼闊的天穹之下渺小如我，面對自己無以名狀的惶然，無從表達自己的心意。 希巨的唸辭，表達了我們做紀錄片的意義於一二。希巨的儀式，也替我這十年的作為，及一路伴隨我的家人朋友們的良善心意，做了最貼切的總結。-湯湘竹

In the Dulan tribe of Taitung where the sea and the mountains meet, the director met an Amis youth, Siki Sufin, a wood sculptor. He learned that there were a group of youngsters that vanished when KMT took over Taiwan; they were brought far away to China to fight in a war that had no purpose. The director began his search from Dulan with Siki interviewing the remaining Taiwanese veterans, focused mainly on the Amis aborigines. During the search in Dulan tribe of the remaining Taiwanese veterans at south of Taitung, Siki petitioned the elders to erect a sculpture at the coast of Dulan to remember the fathers and uncles that were ...
