When Kate’s nasty video chat with her boyfriend is unexpectedly cut short, she doesn’t know what to do with the rest of her evening. Fortunately, her best friend calls and invites her out for a night on the town, but first she needs some help with some research she's been doing - research that's not exactly homework. After doing her best to help, Kate finds out that Casey and her mom have been volunteering for a pharmaceutical company that has achieved unexpected success with a new genetic modifier. What effect does the pill have? Hint: Kate's extremely happy with the results. But what happens when Casey’s sister walks in on the action?
