Chen Tian returns to Beijing after years in the Great Northern Wilderness, only to find his family's spacious courtyard home illegally occupied by the notorious Widow Jia and her clan. Transmigrated into this era with memories of a future where neighbors scheme and steal, Chen Tian refuses to be a pushover. Upon arrival, he faces immediate hostility from the selfish matriarch, who claims the house as her own and insults his rural background.

Unlike his past life or the original plot, Chen Tian leverages his status as a qualified engineer and the support of street officials to fight back. As the courtyard's various factions—from the hypocritical community leaders to the opportunistic thieves—gather to watch the drama unfold, Chen Tian prepares to expose their greed. With a sharp tongue and a determination to reclaim what is rightfully his, he turns the tables on the bullies, setting the stage for a satisfying confrontation that could send the wicked Widow Jia straight to a labor camp.
