Maddie's mad at her agent and thinks about firing him when a costar is finding work, but she chickens out and seduces him instead. Meanwhile, Arlo, Frank and Thelma confront their fears after they're inspired by Maddie.
Kirstie revolves around Madison "Maddie" Banks, a renowned Broadway star who finds her life turned upside down when Arlo, the son she gave up at birth, suddenly appears hoping to connect after his adoptive parents have died.
However, Maddie doesn't exactly see nerdy and schlubby Arlo fitting in with her luxurious lifestyle. But when Maddie's assistant and best friend, Thelma, and outlandish driver Frank encourage her to give Arlo a chance, Maddie is shocked to find that perhaps she has motherly instincts after all.
