Na Dow, who grew up lying, stealing and fooling around, decides to straighten out and takes his first steady job as a courier. The job is simple: hail a cab at sunrise, deliver a package to a close friend of Na Dow’s boss, and return on the same cab by sunset. Little does he know that he would be delivering heroin of top-notch quality. Na Dow hesitantly gets on a shabby taxi driven by the seemingly carefree Old Xu, a Hong Kong native who came to Taiwan 25 years ago and somehow decided to stay. Na Dow's plan to reform himself and Old Xu's wish for a peaceful life take a downturn when they become the target of a mob attack. The drugs and the money are gone, and Old Xu and Na Dow are held hostage in the trunk of a car.
