What happens when Grace, a small-town, strict and prissy head teacher turns into a sexually attractive and unprejudiced MILF? Due to a "mutant" accident, the new Grace is a shattering and outspoken woman tackling her family, her colleagues, her students and the whole town by triggering the emotion that distinguish the relationship with our body and our intimacy: embarrassment. She is free and explicit long enough to shock those who used to accuse her to be a bigot. 

With humour and self-mockery, the musical talks about stereotypes and prejudice of middle-age sexuality, menopause, self-discovery and, more than everything, about the joy of living.
