The Administrative Enforcement Agency has arrested Grandma Qiu-tao, now 70 years old and still a pushover, for owing millions in taxes from her family’s wholesale crystal business. Upon posting bail, Qiu-tao investigates and discovers that her husband, Chen Zong-long, has taken advantage of the opportunity to empty the store’s crystals and disappear without a trace. Left to handle the massive tax debt and court case alone, she later finds out that he has started a new company with a “close female friend.” The mild- mannered, hard-working and honest Qiu-tao reaches
her breaking point. She calls upon her two former prison friends from a previous stint 40 years ago — Grandma Yue-jiao (75) and Grandma A-Zu (61) — to help her. Determined to seek justice against her irresponsible husband, the three grandmas, each with contrasting personalities, reunite. They had all served time for different reasons such as family, bad influences, and financial temptations. This time, with their blurry vision and arthritic joints, they prepare for an outrageous and daring heist to reclaim the precious crystal geodes that Chen Zong-long stole.
