A young couple are living a quiet and happy life, until the husband suddenly begins howling uncontrollably.

A man and woman are married and living ordinarily. She loves him. He loves her. They will continue on - not quite. The man begins undergoing metamorphosis and becomes uncommunicative, enraged, howling and ultimately an out-of-control beast who needs to feast on flesh to sustain himself and survive. Many shall suffer.—aghaemi
