You may have to buy the movie - it’s not on Netflix to borrow. Maybe your library has it? They most likely have the book. It was written sometime in the ‘90’s, I believe.
I love a good murder mystery! :)
“A Simple Plan” is on Amazon Prime.
It’s on Amazon Prime. I made it to the point that one of them kills a farmer who was headed in the general direction of the downed plane. They seemed too damned stupid to care about at that point. Oh, and at no point did they ever actually even try to stick to the simplementation olan.
