If you know in advance what kind of life you are going to face, will you still have the courage to come? Wu Linglan, Shen Guangyao, Wang Minjia, Chen Peng, Zhang Guoguo, several young people are full of desires and are moving forward in four extraordinary time and space. Wu Linglan (played by Chen Chusheng) was full of vigor when he set out, but soon lost his way on the way. Shen Guangyao (played by Wang Leehom) voluntarily participated in the most brutal war. He has been trying to do things that scare him but are important. Wang Minjia (played by Zhang Ziyi)'s initial mistake was just to tell a little lie for vanity; the initial trouble was just to choose between two excellent men. But fate dragged her into the abyss of being cursed by everyone. Chen Peng (played by Huang Xiaoming) put love before his ideals, but love did not put him first. He said, "I have someone to take care of", even if it means going against everyone and being exiled thousands of miles with her. Zhang Guoguo (played by Zhang Zhen), in a workplace full of intrigues, "winning" is his habit. In order to win, he always counters the opponent's moves and strikes first. But one day, he faces a choice that is more important than "winning". These young people ushered in the most brutal test at their best age and created a youth legend that will never fade.
