Susan has long been the eccentric and self-absorbed member of her family, coasting through life with their reluctant backing. However, she suddenly finds herself in middle age, lacking a career, a partner, and with her family growing more distant. Determined to change her circumstances, Susan resolves to take control of her life. Yet, having never truly relied on herself before, she faces a genuine (and comical) challenge in transforming into the person she has always aspired to be, entirely on her own.
