Lucky At Bat follows the story of a young boy named Jack and his two rescue rats-Lucky and Gus-Gus. When Jack discovers that Lucky has a talent for baseball, the little rat becomes the mascot and secret batting coach for Jack’s Little League team. Unfortunately, a rival team considers Lucky’s presence “cheating,” and tensions rise, resulting in a terrible accident. Lucky and Jack wonder if maybe a ballpark is no place for a rat.

Now it’s up to Jack’s teammates and Gus-Gus to show both Lucky and Jack that they are special and important, and they should not give up on their dreams, no matter how big those dreams may be.
