Stevens carries the 30-minutes with a top-notch turn. As the daughter of upper-crust parents, Jana's (Stevens) growing increasingly bored with her cloistered life inside a lavish mansion. Seemingly to lack very little, the three live in extreme comfort tended by a crew of super-obedient servants. So why is Jana unhappy when so much is at her fingertips, and everyone else seems so contented.
I expect Stevens' strong performance was aided by the deep unhappiness of her personal life, unfortunately one of Hollywood's most tragic. And since there's not much action or change of scenery, much viewer interest depends on Stevens' abilities. The premise, however, is an interesting one, delving into questions of personal identity, and how much of that depends on the reality of recollection. There are a number of holes in the logic as the story progresses (e.g. how is it that Jana craves freedom), but still the story compels. For another reviewer and myself, there is a striking moment when the maid smiles eerily after tumbling down the stairs. It forebodes tellingly what is later revealed.
All in all, it's an uneven episode that should have done more showing (like the smiling maid) and less telling. Nonetheless, it's an interesting half-hour, serving too as a brief tribute to the tragically star-crossed Inger Stevens.
