Machines are made by men for man's benefit and progress, but when man ceases to control the products of his ingenuity and imagination he not only risks losing the benefit, but he takes a long and unpredictable step into...the Twilight Zone.James Elwood is called in to replace a computer programmer named Fred, when Fred proves unable to resolve a functional error in the world's most powerful computer, codenamed Agnes.
Elwood fixes the problem, and emboldened by his promotion, asks out a co-worker, Millie, in whom he has long held a romantic interest.
Agnes tells Elwood his best course is to introduce her to an "inferior type male", and suggests third-floor programmer Walter, a handsome womanizer.
Elwood is called back to work due to the deadline for his current assignment being moved up three days, allowing Walter to hustle him out of his apartment and spend the evening with Millie.
Otherwise, you may find yourself like poor Elwood, defeated by a jealous machine, a most dangerous sort of female, whose victims are forever banished... to the Twilight Zone.
