Although Xiao Ming (Zhang Ruiyu) lives a wealthy life without worries about food and clothing, his broken family and busy parents rarely make him feel the warmth of family affection. Even on his birthday, his parents can't spare time to accompany him. His mother gave Xiao Ming a large sum of money to celebrate his birthday by himself, so Xiao Ming invited a large group of classmates to have a party in the huge but empty villa. Driven by vanity, Xiao Ming boasted that his father and mother loved him very much, and even the password of the safe was set to his birthday. The speaker was unintentional and the listener was intentional. The freight driver Liu Bei (Qiao Shan) and the hair salon owner Zhuang Qian (Xu Juncong) took Xiao Ming's words to heart. At night, the two sneaked into Xiao Ming's house with their own intentions. Who knew that there, the two met a "colleague" named Jin Yanzheng (Cui Chengguo), and the whole incident began to develop in an uncontrollable direction.
