"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."
