Follows 40-year-old Liza (Foster), a suddenly single mother who tries to get back into the working world, only to find out it's nearly impossible to start at the bottom at her age. When a chance encounter with a 20-something guy at a bar convinces her she looks younger than she is, Liza tries to pass herself off as 26 -- with the help of a makeover, courtesy of her best friend Maggie (Mazar). Armed with new confidence, she lands a job as an assistant to the temperamental Diana (Shor) and teams up with her new co-worker and fellow 20-something Kelsey (Duff) to make it in the career of her dreams.
