Eliot Shag's inspiration for his next Ace Hart Adventure comes from his television repair man who's nostalgic for the good ole days of radio.

Coleen Barker, Eliot's neighbor, asks Eliot to puppysit her nephew Pomeroy.

Bruno is convinced that aliens are invading Dog City. Eliot decides to take this as a cue for his next Ace Hart Adventure.

Arch bad dog Bugsy Ville is sentenced to the Dog Pound after naming his dumb dumb nephew Bruiser as the gang's new Dogfather. But even with Ace and Roise hot on his tail, Bruiser somehow pulls off a series of brilliant crimes that prove every dog does have his day!

Dog City's annual shipment of flea powder has been pilfered and Hijacked And Ace Hart the local flatpaw along with the lovely Chief of detectives Rosie O'Gravy are itching to sniff out the culprits! Ace finds himself barking up the wrong tree, untill though a poetry spouting bow wow named Mad Dog that lends Ace and the flatpaws a paw!

Eliot swaps superhero stories with Artie and decides it's time to introduce a superhero to Dog City. However, when the "Watch Dog" quickly rises to star status, Ace gets jealous.

Eliot helps Artie to understand that a hero doesn't have to be a superhero. Sometimes heroes are just ordinary dogs doing ordinary things, like his mom, Terri. Ace and Bugsy battle it out for the "Hero of the Year " award. Mr. Moogie saves the day by shrinking himself small enough to go into the stomach of the Presidog to fight a patch of bad grass. We also meet with the Woof Pack as they go rocketing off to the supermarket in search of biscuits.
