Zack is a teenage genius. And it's not an easy life. His parents don't appreciate him, his lab mouse bites him, the local rock group has it in for him, and the family dog can't keep his nose out of the test tube. Maybe that's why Zack's experiments tend to have unexpected results!
Fortunately, there's Loretta. She believes in Zack. In addition to being the girl of his dreams, Loretta claims to have a time machine in her basement. Does she really? Zack feels he owes it to the world to find out.
