Stop me if you heard this before. Miss Dai is a real handful of a mother-in-law, who literally worries her daughter-in-law sick. When the poor woman is finally hospitalized for exhaustion, Miss Dai starts to feel some judgmental vibes from her family. Walking the streets in an Edward Hopper kind of mood, Miss Dai wanders into a mysterious photo studio. She wanders out restored to her perky self at twenty.
Initially, Miss Dai tries to avoid her friends and family, but she when her spoiled grandson hears her rock an open mic, he recruits her for his scuffling back. Transforming them from punk rock hacks into a straight-laced pop group, Thanh Nga (as she now calls herself) attracts the eye of a handsome music producer, both professionally and romantically. The leads to some awkward jealousy from her grandson and Brother Be, the torch-carrying old crony who knows her secret.
