The Sleeper

It's 1981 and the girls of Alpha Gamma Theta sorority are having a party. Amy, sick of living in the dorms, invites her roommate Ava to attend the party with her in hopes that they'll both become Thetas.

As the girls arrive, so does an uninvited guest watching them in the shadows. Amy's choice quickly becomes a nightmare as the Theta girls begin to disappear one by one.
