Brooke and Cameron are after some extra credits to pass the year when they come across an advert offering some... if they take part in a psychological experiment. Willing to do anything that doesn't actually involve work - they sign up.
They discover the experiment is a study into the sexual conditioning of women - and if straight girls can be turned lesbian! The girls find themselves being studied by a cute grad student who is going to test just how straight they are. As they go through one sexual experiment after another, the girls start to realize they might not be quite as straight as they thought!
