New owner Lu Chengan brings his postoperative mother to move into their new home, only to find that their yard has been unauthorizedly used by neighbor Zhao Wenli and his son to host a paid birthday party, locking them outside. The other party not only refuses to back down, but also cuts trees and damages the yard's ground without permission. After undergoing neighborhood disputes and community mediation, the Zhao family distorts facts to incite public opinion. Lu Chengan preserves evidence, goes through legal channels for rights protection via professional assessment, and finally wins one hundred thousand yuan in compensation. As the storm comes to an end, he and his mother are finally able to peacefully enjoy the calm life of their own small yard.
