Kirstie revolves around Madison "Maddie" Banks (Alley), a renowned Broadway star who finds her life turned upside down when Arlo (Eric Petersen), 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 (Rhea Perlman), and outlandish driver Frank (Michael Richards) encourage her to give Arlo a chance, Maddie is shocked to find that perhaps she has motherly instincts after all.
本季情节贴合80年代的标志性事件，包括核战电影《浩劫后》（The Day After）的上映、前总统里根的星球大战演说、大卫-科波菲尔让自由女神像「消失」的神奇魔术。第四季的核心情节是「这个苏联间谍家庭如何生存（如何自保）」。与此同时，被囚禁在俄罗斯的双重间谍Nina有可能重返美国，与前情人Stan Beeman团聚。请注意这个「有可能」，因为现在谁也说不准。Jennings家的小儿子Henry本季有更多出境时间，他在前两集中经常与邻居Stan待在一起。上一季关注了Paige的变化，或许这一季要关注Henry的变化？此外，Keri Russell的怀孕不会写进剧情中。FX暗示该剧可能在本季或者第五季结束。
