快遞員在夜間子彈列車車頂奔跑，滑過低矮隧道、跳過障礙，最後單手懸在深淵上方

提示詞

開場鏡頭：一列高速列車在夜間飛馳穿過群山。快遞員沿著車頂奔跑。列車突然駛入一座天花板低得危險的隧道。快遞員立刻伏低身體，從隧道下方滑過，頭頂幾公分處火花四濺。緊接著，另一個障礙物擋住車頂去路。快遞員來不及停下，只能縱身躍過。落地時卻出了差錯。快遞員從列車側邊滑落，單手懸掛在深淵上方，下方的地面飛掠而過，模糊成一片。快遞員借助慣性和純粹的力量，把自己盪回車頂，繼續奔跑。
結尾鏡頭：列車飛速駛入另一座隧道，快遞員緊抓著列車前段。

Opening shot: a bullet train races through the mountains at night. The courier sprints along the roof. Suddenly the train enters a tunnel with a dangerously low ceiling. The courier drops flat and slides underneath while sparks explode inches overhead. Immediately after, another obstacle blocks the roof. With no time to stop, the courier leaps over it. The landing goes wrong. They slip off the side of the train, hanging with one hand above the abyss while the ground blurs below. Using momentum and pure strength, they swing themselves back onto the roof and continue running. 
Final shot: the train rockets into another tunnel while the courier clings to the front section.
