At the beginning, a narrator speaks as we are shown a residence and the dog named "Angel" that guards it. The viewer is shown the top of a cistern, with "David" the narrator (played by Kent Smith) at the bottom of the cistern. Here's the flashback to tell his story...

When David is picked up for vagrancy, someone pays his fine, and has a proposition for him: He is to pretend to be a millionaire, who had disappeared several years prior. Even the millionaire's wife can't tell he is an impostor, but things start to go wrong. The man he is impersonating wasn't very well liked, and David must find out why. Viveca Lindfors gets top billing as "the wife", but it's Janis Paige as the sister- in-law who (rightfully) steals the show. Watch for Monte Blue as the Sheriff. The acting isn't anything special, but the story is mildly compelling, and since we know right from the start that David ends up in the well, we get hooked on finding out how he ends up there.

Written by Richard Sale, who had several novels and screenplays made into films. This one IS available on DVD, although you can catch it on Turner Classic Channel about once a year. Directed by Richard Bare, who wrote a book on the proper technique on film directing.
