Clark, a young Mathematics major at University, thinks she's found the best
deal for student housing: a group of squatters who live in an abandoned hospital
secretly. The quirky residents let her into their community provided she follow
the rules, including not telling anyone about her living arrangements. All seems
wonderful, until she discovers that the reason that the hospital was abandoned
was a series of murders in the 1940's by a strange "shrieking killer" who was
never captured - and the discovery that someone who's living in the hospital is
using occult means to bring back the "Shrieker," a demonic force summoned and
controlled by a human who knows the proper procedure. When strange occult
circles are discovered, Clark finds herself the main suspect, because she is
the newest resident.
