Next time you rent an apartment, you might check to make sure it's not the doorway to hell before you sign the lease. Alison (Cristina Raines, who vanished from the Hollywood scene in 1987) is a suicidal model who figures this old and roomy place will offer a respite from her rough life. When she complains about the weird and loud neighbors (including an unforgettable and deliciously nasty Beverly D'Angelo, who rubs her crotch to, er, completion when Alison is over for coffee), it turns out no one else lives there. Is it a hallucination or demons? Either way, this is one hell of a sick little horror flick. Watching for stars then and now to make their appearances can alone make the film worthwhile.
