This spin-off of the hit cartoon Martin Mystery (originally based on the bestselling comic book by Alfredo Castelli) takes place in an alternate universe where the two main characters never met.
Diana Lombard is a cute, smart, sassy teenage girl with a passion for learning. Along with her two best friends, Jenni (a pretty and popular girl) and Kevin (a fellow overachiever and former penpal), Diana attends Spencer Grove High School (a fictitious high school in Southern California) where she experiences new and interesting subjects, as well as unusual aspects of everyday teenage life.
