Vector the Crocodile and his crew from Chaotix Detective Agency - consisting of himself, Julie-Su, Espio the Chameleon and rookies Charmy Bee, Mighty the Armadilo and Ray the Flying Squirrel - are out to investigate and report a crime surrounding Westopolis.
The film begins with a convoy being sent to somewhere in Mobius. Suddenly, a green crocodile jumps on one of the cars. The Crocodile rips one of the cars, as a purple chameleon sneaks in and takes control of one of the cars. Later on, the convoy ends up being destroyed as the figures are shown fully; Vector the Crocodile, the head of Chaotix Detective Agency, and Espio the Chameleon. Their mission: to stop a gang of thieves who had just stolen Eggman Technology and plan to sell it for pirates at the docks of Westopolis.
