In ACME's New York branch, the Chief informs agent Julia that some of the world's greatest treasures have been stolen. The Chief suspects the thefts to be the work of Carmen Sandiego, but there is lack of evidence to confirm it. Julia along with Adam Shadow are sent to find the thief and recover the treasures, before news of the theft reaches the public. Matt Forrest provides technical assistance during the mission. After many investigations around the world and putting together a digital map of Atlantis, it turns out that Carmen Sandiego had been intercepting ACME communications and planned this entire mission. Carmen Sandiego steals the map and heads to South America.
