When members of the nefarious crime syndicate KAOS attack the U.S. spy agency Control and the identities of secret agents are compromised, the Chief has to promote hapless but eager analyst Maxwell Smart to field agent. He is partnered with veteran and capable Agent 99, the only spy whose cover remains intact. Can they work together to thwart the evil world-domination plans of KAOS and its crafty operative?

Bumbling R&D inventors Bruce and Lloyd get out of the lab and into the field as they search to locate their latest invention - which has somehow gone missing. When you're used to spending your day inventing the most cutting edge spy equipment known to man, adapting the stealth and guile needed to become a true secret agent doesn't come naturally. Unfortunately the invisibility cloak that the pair recently collaborated on has disappeared, and in order to ensure that it doesn't fall into the hands of KAOS they will have to master the skills of a true spy. But how exactly does one find an object that's invisible to begin with? As the search gets underway, these brainy inventors are given an eye-opening crash course in high-level espionage.
