James Denton, Lilah Fitzgerald, and Luey in A Girl's Best Friend

UP movie A Girl's Best Friend premieres Sunday, January 4 at 7 p.m. ET. The film stars James Denton (Desperate Housewives, The Good Witch), Laura Mennell (Haven), (The Gourmet Detective), Kirsten Robek (Hell on Wheels) and Lilah Fitzgerald (The Pastor's Wife).

In A Girl’s Best Friend, Penelope "Polka-Dot" Daught (Fitzgerald) is a precocious 11-year-old obsessed with Mark Twain’s “The Adventures of Huckleberry Finn.” With her single mother, Frances (Robek), struggling with chronic illness and money tightness, Polka-Dot is pushed into looking for odd jobs after school for extra cash. While sweeping up around the neighborhood coffee shop, Polka-Dot’s life perks up when she meets K-9 unit police officer Cooper “Coop” Boone (Denton) and his trusty bloodhound, Luey.

Falling instantly in love with Luey, Polka-Dot talks her way into the police kennel and soon badgers Coop into a “part-time job” taking care of his dog. Meanwhile, Coop uses his new free-time to try to rekindle his romance with ex-girlfriend, probation officer Samantha McLean (Mennell). When Francis is hospitalized, Polka-Dot valiantly attempts to fend for herself, rather than go into child services protection. But soon, her attempts to cover up the seriousness of her situation are sniffed out by her new pals, Luey and Coop.
