Colleen Fradejas is your typical introverted bookworm and coffee lover. She cherishes her alone time when she does not have to force a smile and make conversation with people. All in all, socializing has never been her cup of tea. Until one day she meets a group of nine mysterious yet beautiful women while doing her usual morning jog in the park. They hit it off immediately and exchange numbers. The more Colleen spends time with these women, who share little about themselves, the more her interest in them grows. One night, during a sleep-over at their place, Colleen makes a horrifying discovery that leads her to wonder if her newfound friends are truly who they appear to be.
