Oakcrest O'Brian is a nine-year old boy who doesn't believe in Leprechauns. One morning while eating breakfast, a rainbow appears in the kitchen. With the beautiful colors reflecting like prisms on the walls of the room, Oakcrest reaches up to touch a ray of light when suddenly, he disappears from the room, in a rainbow vortex, on his way to Leprechaun City. During his short stay in a place where Leprechauns are real, Oakcrest finds out what is really important.
