Dr. Foster is testing his company's breast augmentation drug on a group of coeds who think they are participating in a sleep study.

When they realize that the drug has certain sexual side effects, Foster makes them a deal: stay on with the study and you will be compensated handsomely for working a couple of hours on the weekends.

The catch? The couple of hours of work on the weekends is not going to be easy, but they might enjoy it. Tara and Kelly have some decisions to make.
