Hidden within the SAT high school verbal and math skills questions is a diagnostic test that also measures the aptitude of students for lying, cheating and killing. If a young woman scores high enough on this covert portion of the exam, she is recruited to join an underground academy known as the D.E.B.S. Four, beautiful, young provocateurs in short, plaid skirts are culled for their first mission: to take down the most evil criminal the world has ever known, at least in the division of beautiful women outfitted in black--Lucy Diamond, D.E.B.S.' lesbian nemesis, also know as "Lucy in the Sky."
