Zelly Fried has finally convinced her parents to let her get a dog, with the help of her grandfather Ace. Unfortunately, said dog (also named Ace) is a shoe-chewing, mud-tracking, floor-peeing kind of dog. Despite Zelly's best efforts to drag Ace (literally!) to puppy kindergarten, his flunking report card says it all: "This Ace is wild." Also wild is the other Ace in Zelly's life. Grandpa Ace has decided to begin dating again and is dining and dancing every night, against his doctor's orders. Determined to get both Aces under control, Zelly enlists the help of her two best friends, Allison and Jeremy (despite the fact that they don't quite see eye to eye). They need to come up with a plan, fast. But how?  It's not like either Ace ever does what he's told.
