Two best friends decide to try out as pledges for an infamous Sorority House. They've heard stories about how a lot of their old traditions for new girls have been harsh and sometimes cruel but have apparently changed since the 80s and 90s after some incidents. The new Sorority House ****** has the new girls meet on the night of their hazing rituals that will determine which ones are worthy. The two friends go through the strange requests including wearing blindfolds, stripping to their underwear, receiving spanking by paddle board, etc. Though one of the friends wants to quit she decides not to look weak and endure. The House ****** tells them this was never going to be easy and that the old sorority practices were too soft and that she has something that will bring them all closer together. She opens a box and reveals a large larva egg. The girls think this is some kind of joke until it hatches and slugs fill the room. The Sorority ****** laughs evilly, telling them all to accept it and not to fight.
The two friends try to escape as each girl is taken over and go into a girl crazed frenzy. They would attempt to leave through a window but one of them is caught and turned. The Parasited friend tries to convince the other to join them and that they made an oath before college that no matter what they would always be together. Scared, the friend accepts and is turned. Things keep escalating with a full on sorority house orgy.
