The Chief meets Smart at a public library to recover a special book. The book is a master list of CONTROL agents but its hiding place has now been compromised. Max and Larrabee transport the book in an armored car to a bank vault, but Max accidentally locks the vault door on both the Chief and Larrabee. As the vault only has a limited amount of air, Max and 99 decide to get an imprisoned safecracker (named "Baffles", a spoof of Raffles) but come back with a convicted master forger instead. Will the Chief and Larrabee be freed in time?
