Successful and single businesswoman Kate Holbrook has long put her career ahead of a personal life. Now 37, she's finally determined to have a kid on her own. But her plan is thrown a curve ball after she discovers she has only a million-to-one chance of getting pregnant. Undaunted, the driven Kate allows South Philly working girl Angie Ostrowiski to become her unlikely surrogate. Simple enough ... After learning from the steely head of their surrogacy center that Angie is pregnant, Kate goes into precision nesting mode: reading childcare books, baby-proofing the apartment and researching top pre-schools. But the executive's well-organized strategy is turned upside down when her Baby Mama shows up at her doorstep with no place to live. An unstoppable force meets an immovable object as structured Kate tries to turn vibrant Angie into the perfect expectant mom. In a battle of wills, they will struggle their way through preparation for the baby's arrival. And in the middle of this tug-of-war, they'll discover two kinds of family: the one you're born to and the one you make. 发现一个美女也算收获。环保电影。我从来不是幽默的女生。讲友情的故事吧。母爱泛滥。是不是温馨的圣诞电影？。改行还是不容易的。失望。想当妈妈也不容易啊。了不起的Tina Fey。 凯特（蒂娜·菲 Tina Fey 饰）是个37岁的女强人，但她除了一帆风顺的事业外几乎一无所有，于是起了做单身妈妈、人工授精生子的念头。可惜“不孕”的体检结果击碎了她的梦想，她只好找到代孕中心，选中了一个叫安吉的金发女孩（艾米·波勒 Amy Poehler 饰）为她代孕。安吉受孕成功了，本着迎接孩子的欣喜心情，凯特做了大量物质准备，阅读大量育儿书籍，也迎接安吉住进她家，但是很快两人发现彼此格格不入，安吉是贫民区女孩，有着许多懒散放纵的坏习惯，而凯特是上流社会女强人，非常注重教养规矩。两人的相处从矛盾频发开始，漫长的九个月孕期充满了不平静……
