David Meng (played by Wang Xun) has always hoped to become a writer. However, it was not until he really embarked on this path that David Meng discovered how difficult this road was. While his career encountered a bottleneck period, the relationship between David Meng and his wife Yang Xiaonan (played by Yu Shasha) also dropped to the freezing point. Not only that, David Meng was diagnosed with cancer and his life was coming to an end. Frustrated, David Meng decided to buy himself a life insurance policy, and the beneficiary filled in his wife's name. After that, he embarked on a suicide trip to Thailand. However, David Meng's suicide plan did not go very smoothly. After repeated failures, David Meng found the killer Bran (played by Jin Shengzhu) and handed the responsibility of ending his life to him. Who knew that Bran seemed cold and cruel, but in fact he was an ignorant and reckless rookie. Not only did he fail to die, but David Meng was also involved in a mysterious conspiracy.
