The Bannister family is back! This time they are travelling to Southern California for the holidays to stay with Aunt Barbara (Shelley Long of TV's CHEERS), who surprises them with a new puppy named Eve (Peyton List of DIARY OF A WIMPY KID). Everyone is smitten with Eve - except for the Bannister's dog, Zeus (Joey Lawrence of TV's BLOSSOM), who sees what a mischievous animal she is when no one else is around. After deciding to run away, Zeus sees Ted and Stewey, two thieves, trying to break into the family home while the Bannisters are at church. It's up to Zeus and his newest sister Eve to join together to save the holidays for their family!
