The Free Nanny's Revenge

Mabel So is treated as a free nanny by her son and daughter-in-law, who forge an Advanced Gastric Cancer diagnosis to coerce her into signing a Last Will and Testament. She gathers evidence, uncovering scams by her daughter-in-law's family to seize her property. She installs cameras, records discussions, and confronts them at the Family Banquet for the will signing. Her in-laws are sent to prison, and her son comes to his senses. She finds a fulfilling later life through calligraphy.
