Olivia O'Hara is over love: She's dumped just two weeks before Christmas and plans to wallow in her heartbreak instead of getting in her u sual holly, jolly spirit. When visiting her family, life throws her a major curveball in the form of a reporter-turned-romantic interest, Casey Rawlins.

Marlo (Academy Award winner Charlize Theron), a mother of three, forms a bond with her thoughtful, surprising, and sometimes challenging young nanny, Tully (Mackenzie Davis).
