Parents are biased in dividing the family, giving all the relocation compensation and settlement housing to the younger brother, and only giving Lin Wan a lottery ticket to offset three hundred thousand. The lottery ticket unexpectedly wins thirty million, and Lin Wan quietly cashes it. The younger brother gambles away the family property and incurs high-interest loans, and the parents force her to take the money, only to discover that the winning ticket was bought by the father, coming to their doorstep to fight for it. Lin Wan relies on the family division agreement and the law to keep the prize money, fights back against the frame-up, and ultimately succeeds in her business, wins a design gold prize, draws a clear line with her original family, and completes self-redemption.
