In this high-tension thriller, a notorious serial killer called "The Trasher" has been captured, and has been locked up in an unusual high-tech mental institution for the criminally insane. However, the female psychiatrist who has been attempting to learn the killer's secrets is suddenly in a position to find out more than she ever wanted to know about him when she finds herself locked up in the asylum after hours, with the Trasher after her trail, and her only ally is a floor-sweeper who may actually be a fellow inmate. Dark Asylum stars Judd Nelson, Paulina Porizkova, and Larry Drake.
