The Grande Adventures of Ace & Indy is a compilation of short adventure stories that revolve around the two young heroes who live in a fantasy world of myth and magic.

When Ace and Indy first meet, they find themselves in each others' way and, thanks to being in a rush, their egos clash. An epic battle between the two highly skilled adventurers ensues and, because they are so evenly matched, neither one lands a single blow on the other.

Eventually, their fights ends in a draw brought on by exhaustion, and since they can't even stand up, the boys' only option is to talk though their conflict. By talking, not only do they realize that they've both acted foolishly, but by forgiving each others' follies, they end up becoming best friends.

From there, each episode pits the young heroes against mythical creatures and magic-wielding beings that will challenge more than just their physical skills.

To resolve these conflicts, the heroes must make new friends and practice strong character traits so that, in the end, not only are the challenges overcome, but valuable life-lessons are also learned.
