Several prison convicts escape within a short space of time, leading Steed to conclude that someone is running an organization specializing in "springing" inmates ahead of schedule. Going undercover as a prisoner, Dr. Keel traces the clues to a finishing school for young women. Another of Steed's assistants, Caroline Evans (Margo Andrew) enrolls in the school, and as expected, both she and Keel fall into the clutches of the villains before the final fade-out. Written by John Whitney and Geoffrey Bellman, "The Springers" first aired May 13, 1961. ~ Hal Erickson, Rovi
