A bomb-sniffing beagle is fired from the mayor’s office for a faux pas.
That night a mad scientist dognaps him and injects him with an elixir.
The dog escapes, but now has superpowers. He’s adopted by a security
guard – an ex-cop, who’s a widower with a moody teen son, Jack. The boy
discovers that the dog, named Shoeshine by dad, has super powers, but
it’s their little secret. While Underdog saves people in distress, the
mad scientist and his underling continue their plot to catch him and
take over the city. There’s also a girl Jack likes who has a dog that
Shoeshine takes a shine to. Will every dog have his day?
