A modern youth travels back in time to Zhou Yun, a rural boy from the 1970s. He takes over the identity of the "dog licker in the village" and has just been cheated on by his ex Zhao Xiuhua and broke off the engagement. He accidentally rescued Chen Yuan, who was isolated because of his status as a "capitalist", and expressed his feelings with an egg, regardless of his "Black Five" label. Upon seeing this, Zhao Xiuhua intervened from a "class standpoint". Zhou Yun got rid of his cowardice and exposed his hypocrisy, and gained the support of his parents to prepare for the marriage. Unexpectedly, Zhao Xiuhua caused a disturbance on the day he received the certificate.
