Whoever You Are, Honey (1970)

On the Santa Cruz waterfront lives a young woman and her elderly roommate, an oddball pair who are the last vestiges of a town taken over by the tech elite. But when a new couple moves in next door, the young woman’s once secluded existence is irrevocably disrupted, and she is forced to face the fact that on the outskirts of Silicon Valley, nothing is off-limits, and what was once considered dystopia is now a reality in her own backyard.
