Totally Spies! (2002) : 5x7

As the girls look over the class catalogue for their first semester, they are delighted to find a course called “Espionage 101.” Considering that they are actual Spies, Sam, Clover and Alex decide to sign up and get an easy “A.” Once in class, the professor takes an immediate liking to the girls and commends them for their extensive knowledge of the curriculum. He even picks the girls to play the role of infiltrators in a class exercise recreating a “famous espionage” event from the past. As the girls carry out the faux mission (which involves stealing a top secret weapon which has the capacity to inflate the earth to the point of explosion) they are certain they will all get perfect grades. But what they actually end up getting is arrested. It turns out that the reenactment was a ploy by the professor to obtain a real secret weapon and have the girls take all the blame. But when the girls try to plead their case, no one believes. Can the girls break out of prison and stop the evil professor before he uses the weapon to destroy the world? In a b-story, Sam, Clover and Alex all get part-time jobs at the campus coffee shop.
