Which episode features a woman who sees her exact double?

The Twilight Zone episode featuring a woman who sees her exact double is “Mirror Image.” Millicent Barnes waits at an isolated bus depot when increasingly strange events make her question reality: her luggage seems to move, staff members insist she has already visited places, and she finally sees an identical version of herself.

Written by Rod Serling and directed by John Brahm, “Mirror Image” originally aired on CBS on February 26, 1960, as the 21st episode of the first season. Vera Miles plays Millicent, while Martin Milner plays Paul Grinstead, a fellow traveler who tries to reassure her.

The episode is a classic doppelgänger story. Millicent believes her double comes from a parallel world and intends to replace her, while Paul interprets the incidents as confusion or a mental breakdown. The ending preserves that uncertainty: after Millicent is taken away, Paul notices that his own valise has mysteriously disappeared, suggesting the phenomenon may be real after all.
