Only thing I remember: a lady is lying on the desert floor, near a cabin, some invisible presence walks towards her and a man, who grabbing an axe, throws it towards the presence which turns out to be a skeleton. The axe gets stuck in the skeletonīs chest. Black and white, Iīd say 50s. I saw it when a child (in the 70s) and the scene came to me, vividly, while recovering from a car crash. Sorry, I do not remember anything else. Thanks.
