New doctor Liz Asher arrives at Darkplace Hospital, where a mysterious cat portends disaster. Dr. Rick Dagless, M.D., must act in time to prevent unspeakable evil from leaking out from a portal to Hellmouth under Darkplace Hospital.

Somewhere on the wards of Darkplace Hospital, a man gives birth to a giant eyeball which brings out paternal instincts in Dagless, still grieving for the loss of his half-human, half-grasshopper son. However, the eyeball could be a potential killer.
