Twenty college girls live at the Alpha Chi Omega Sorority House. They recently attended a conference on living green and came home with poor grades on that front. Those computers, mini refrigerators, and hair dryers create a staggering utility bill. When they see the truckload of plastic they toss every month, the lesson hits home. Classes officially start when Annabelle and Holter give them their assignments, with the girls' final just a few weeks away. Will they get an 'A' in waste management or will it turn out to be a wasted opportunity?
