"Pluto" comes out of nowhere and quickly makes himself at home with the Davis family, who are on the brink of falling apart. Dad (Michael Cassidy; Argo, Batman v. Superman: Dawn of Justice) is a career-driven workaholic who is neglecting his marriage and family. Mom (Sarah Lancaster; Chuck, Saved by the Bell: The New Class) is at her wit's end raising three young kids. The last thing they need is another mouth to feed. Or is it? In just a short time with the Davis family, Pluto the "wonderdog" manages to save a lost toddler, bring comfort and companionship to a hurting 9-year-old boy (Connor Corum; Heaven is for Real), help restore a marriage, and repair a broken father-son relationship. Pluto is not only a guard dog – he’s a guardian angel.
