Dr. Stillman arranges to have his human-looking robot signed up as the star pitcher of the Hoboken Zephyrs. The team zooms to fourth place thanks to Casey. After he's beaned by a ball, a doctor discovers Casey has no heart. The rules say nine men make up a team, and without a heart Casey is not a man. Dr. Stillman gives Casey a heart, but he becomes too compassionate to strike out other players. The Zephyrs lose the pennant, and Casey is washed up in baseball. Dr. Stillman gives the coach, Mouth McGarry, Casey's blueprints as a momento. Looking at them, Mcgarry gets a sudden inspiration, and chases after the doctor.
The series was a collection of various tales that range from the tragic to the comedic. They may be scary or just thought-provoking. Most episodes have unexpected endings and a moral lesson. But, no matter what, it's "a journey into a wondrous land, whose boundaries are that of the imagination".
