The Twilight Zone, Season 3

Narrator:
Your attention is drawn to the residence of the Brockman clan. An ancient mansion, its paneled walls polished by darkness; a lifeless, soundless place, upon which a greater darkness has fallen. The object of the deathwatch, Selena Brockman, grand dame of the menagerie, who lies in her bed in an inch-by-inch battle with death, trying somehow to reach a compromise instead of a capitulation.
