Hilda and her companions arrive at a legendary haunted basement to stock supplies. After an unsettling encounter where a driver abruptly flees without payment, Hilda faces eerie events, including a mysteriously slamming window. While organizing the basement, she accidentally reveals a hidden stone slab covering a dark, deep hole emanating a foul, sweet odor. Shining a flashlight inside, she finds ancient carvings or dried blood on the walls. When she peers into the hole, a horrifying sight causes her to scream, leaving the nature of the hidden space and its danger unresolved.
