The Tingler

Dr. Warren Chapin, a pathologist, discovers that extreme fear can create a parasitic creature within the human body, which he names the "tingler." Dr. Chapin's experiments reveal that this organism attaches itself to a person's spine and feeds off their fear, causing fatal spinal damage if not released through the human act of screaming. Intrigued by the potential implications of his discovery, Dr. Chapin collaborates with his assistant, David, and takes an interest in the peculiar case of Ollie Higgins and his deaf-mute wife, Martha. Martha is unable to scream due to her inability to speak, making her an ideal subject for Chapin's investigation.

As Dr. Chapin delves deeper into his research, he subjects himself to extreme measures to understand the tingler's power and manifestations more thoroughly. However, things take a terrifying turn when the creature escapes and threatens everyone around it. The spine-chilling events prompt frantic efforts to capture and control the tingler before it inflicts further casualties. The tension escalates as Chapin races against time and his own fears, uncovering unsettling truths about the nature of terror and human vulnerability. Crafted with an atmosphere of growing dread, the pursuit of scientific exploration spirals into a mix of horror and suspense.
