Festive comedy in which an unemployed advertising executive finds herself working as a babysitter at Christmastime. Ally (Emmanuelle Vaugier) is an up-and-coming star in the advertising world, brought down by one disastrous pitch. When Ally lays a little too much emphasis on weddings when trying to pitch to chocolate magnate Danny Donner (Dean Cain), recently stood up at the altar, her boss fires her. Ally winds up at the door of rival advertising executive Samantha Ryland (Cynthia Gibb), who offers her a job - as nanny to her children, Jackie (Sierra McCormick) and Jonas (Jared Gilmore). Samantha promises that the children are well-behaved, but Ally finds them a little too well-behaved and decides to bring some Christmas fun into their lives.
