The Glass Mansion is an old house, maybe the oldest of the small forgotten town of Neptune, on Texas. Built long years ago, passed for the Northglass family, generation per generation. Obviously, some people left, some people stayed. But, no one ever discovered the truth behind the magic in that place. Now, after years away from home, Theodore Northglass is murdered with his wife, and their kids are sent to live with their uncle in the Glass Mansion... Based in Locke & Key Netflix show.
