DESCRIPTION: (from Hallmark's press release) Ever since their mother’s death three years ago, Ben (Uriah Shelton, “Ghost Whisperer”) and Emily (Natalie Dreyfuss, “National Treasure: Book of Secrets”) have driven their father (Brennan Elliott, “The 4400”) crazy, going through one nanny after another. No one will take the job until Kate Hewitt (Vanessa Marcil, “Las Vegas”) comes along. When not only her brother but also her father starts to like Kate too much, Emily pulls out all the stops to drive her away. It’s only after she succeeds that Emily realizes how much Kate means to all of them and moves heaven and earth to bring them all back together as one happy family. “Nanny Express” premieres Saturday, January 3 (9 – 11 p.m.).
