The Outer Limits 1963 S1 E 26 The Guests

Wade Norton, a young drifter, finds an old man dying by the side of a remote country road. He picks up the man's pocketwatch, which contains a large photo of a young woman. Seeking help, he enters a mansion he sees atop the hill, whose inhabitants are surprisingly unhelpful but uncannily curious about the age of the man whom he found. With the exception of a soulful young woman whose image is in the watch, all seem mean-spirited and uninterested.

Trying to leave through the front door, Norton is forced backward and upstairs by a mysterious compulsion to discover that the house is the lair of an amorphous, gelatinous alien being who is keeping the group of desperate humans suspended in time until it can comprehend the disposition of humanity. It interrogates him then returns him to the group residing in the house where he is to learn the reason for their captivity.

The young woman, knowing the potential fate of the drifter, leads Norton to an escape route, which is through a gate attached to a small cemetery plot accessible from the mansion. However, she discloses to him that she cannot accompany him through the gate because all her years will catch up with her, and she will die. Thus, the drifter chooses to remain with her in spite of the warnings. As she realizes he will be trapped among them for eternity, she departs through the gate herself and, having eschewed her protection from the passage of time, withers and turns to dust. The observing alien has found the factors missing in its equation: love and self-sacrifice. Releasing Norton, who has discovered in himself hope, it proceeds to deconstruct the house and destroy its tenants. The mansion returns momentarily to its true appearance, that of a rock shaped like an enormous brain, and then disappears.
