Rod Serling's seminal anthology series focused on ordinary folks who suddenly found themselves in extraordinary, usually supernatural, situations. The stories would typically end with an ironic twist that would see the guilty punished.
The sweet and perky Barbara, the sunny Janis, and the responsible Sandra are a trio of young and attractive nurses who work in the psych ward at a hospital. The threesome really have their hands full dealing with nutty patients, creepy stalkers, and black revolutionaries.
