If you Google the name Belle Gunness, you will understand the gist of it. She was born Brynhild Paulsdatter Størsetjare. She emigrated from Norway to the United States in 1881 and changed her name to Belle Gunness, probably to get a more American-sounding name for herself and get as rich as humanly possible without doing any real work. This fails terribly and she sets alterative plans in motion. From what's known in history, she killed her first husband in the year 1900. But will it stop there? The movie doesn't need any form of exaggeration or adding to the story. It's already as gruesome as it can possibly be.
