Aliang (played by Fu Mengbo), a 27-year-old insurance agent who is tired of the world, thinks about how to die all day long. Life is just a repetitive needle jump for him. It was not until one day that he found the posthumous work "Life for Sale" by Japanese literary giant Yukio Mishima that he figured it out... Even if he wants to close down, he should have a clearance sale first! But he didn't expect that this life was not popular on the Internet. Just when he was discouraged, Aliang learned that his neighbor Chen Yuzhen (played by Zeng Zhiqiao)'s son was dying and needed a heart transplant. Just when he was hesitating whether to donate his heart, a beautiful CEO Shen Jing (played by Cai Shuzhen) offered a sky-high price to buy Aliang's life for human experiments. At the same time, a gangster boss sent a killer Guibi (played by Li Mingzhong) to kidnap his parents and threaten him to sell his life. Aliang never expected that his worthless life would be scrambled for now! But there is only one life, how can Aliang get out of it?
