Brother Xiong (Lin Hongyin) and Brother Le (Zeng Weile) are childhood sweethearts. They have been peeing and playing in the mud together since they were young, so there is no need to say much about their feelings for each other. When they grew up, they went to the same school and both became famous problem students on campus. They skipped classes, fought, danced, and smoked with a bunch of friends, but even so, Brother Xiong and Brother Le never crossed the boundaries of the law and caused any real trouble. Brother Le met a group of gangsters in society and was brought into the circle of gambling. From then on, he was out of control and went further and further on the road of breaking the law. Brother Xiong saw it in his eyes and was anxious in his heart, but he had no way to deal with it. At the same time, Brother Xiong's behavior became more and more excessive, and gradually, his friends and confidants began to stay away from the two.
