The Mystery of the Missing Taxicabs

"Canadian super spies Agent Diamond and Charming Guy are back, this time to try to save New Year's Day. The evil genius Dr. Sinister has stolen the Psycho-Cab-O-Meter, a device for psychically summoning taxicabs, and has re-engineered it so the cabs will never come. It's up to Diamond, Guy, and their allies to put a stop to Dr. Sinister's nefarious plans while at a New Year's Eve cocktail party."
