Kelsey makes her debut as a publisher, quickly realizing that the company is in trouble; the new regime - and a revelation about Liza - sends Diana into a crisis; Josh finds out the paternity of Clare's baby.
Based on the novel by Pamela Redmond Satran, "Younger" follows 40-year old Liza, a suddenly single mother who tries to get back into the working world, only to find it's nearly impossible to start at the bottom at her age. When a chance encounter with a young 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. Armed with new confidence, she lands a job as an assistant to the temperamental Diana and teams up with her new co-worker and twentysomething Kelsey to make it in the career of her dreams. Now she just has to make sure no one finds out the secret only she and Maggie share.
