I Found What Was Living Beneath My Mother’s Tennessee Cabin

Terry returns with his girlfriend Vera to his mother’s secluded mountain cabin in Crosby, Tennessee, to clean up her property. Upon arrival, Terry finds the cabin in severe decay, discovers strange bones hidden near their campsite, and experiences unsettling encounters with a shape-shifting entity that mimics the people around him. After being rendered unconscious, Terry is captured by the creature—which is revealed to be the Cherokee myth Spearfinger (U'tlun'ta')—and discovers his brother Nathan has been brainwashed into serving it, while his true mother and Vera have both been murdered.

Escaping from a basement filled with the monster’s past victims, Terry flees the isolated property and reaches a neighboring house for help, only to discover the creature has already arrived before him, disguised as his mother once again.
