It’s a canine caper when Murphy (Just Jesse the Jack), a charming pup with telepathic abilities, escapes a government scientist (Dominique Swain, Face/Off) and runs straight into the loving arms of two young brothers (Walker Mintz, Nessie & Me; and Jayden Hedden, “Betrayed”). But the Washington brass won’t give up their secret weapon so easily, and with a nonsense special forces agent hot on Murphy’s trail (Lauren Parkinson, Avengers Grimm), the boys and their school buddies must hide the pint-sized Jack Russell Terrier from helicopters and drones --and their mom and dad (Amy Holt, I Am Singh, and Rib Hillis, “General Hospital”) who’ve forbidden them to have a pet! Can this unexpected team of heroes, armed with only their wits, their bikes, and a strong bond with Murphy, channel the real spirit of Christmas to save the day?
