Comedy sketch screenwriter Su Lianglan accidentally dressed up as the adopted daughter of the wealthy Lin family. All members of the Lin family are drama queens. From the hypocritical stepmother, the green tea stepsister to the indifferent father, everyone wants to take advantage of her as a "chess piece". Su Liangli wanted to implement the "salted fish" spirit and lie flat to the end, but she found that the family's acting was too bad and full of loopholes, which seriously damaged her professional aesthetic. Thus, a hilarious house fight began, with the "salted fish" adopted daughter "guiding" the whole family in acting. When her stepmother framed her for stealing, she turned on the "live teaching mode" on the spot, commented on her expressions, lines, and moves, and suggested adding light chasing and BGM; her stepsister slandered her at the banquet, so she took out her score board and gave a low score of 2.5 Points from the two dimensions of "emotional rendering" and "core conflict." She used the method of deconstructing comedy to turn all the conspiracies against her into hilarious farces, completely making the entire wealthy family's style go astray. In the end, after exhausting the whole family, she successfully received a compensation for mental damages, left gracefully, and started her own comedy career.
