The horror/suspense thriller feature film GEHENNA opens with an intense scene where a large man is running through the dark woods while screaming. As he approaches an abandon old garage out of the fog and darkness an unseen image(Antagonist) ascends from beneath the fog. Within a minute he over powers the large man who desperately try's to escape from being pulled into the darkness. Three days later a group of hikers accidentally stumble upon badly mangled body parts and quickly report it to the police. Over the next few weeks several murders are discovered. The killings appear to be committed using some sharp object and still no one including the police has a clue how or why they are occurring. Seasoned police detective Roger Cook(Protagonist) is a burnt-out burly looking investigator who is earnestly looking forward to retiring in 10 days.

As Lewis rebuilds his relationship with his father, his romantic relationship slowly falls apart.

Detectives are called to investigate a string of serial killings. Someone or something is killing people and driving locals into paranoid delusions with eyewitnesses saying it's a Sasquatch. The detectives discover that some legends are better left alone.
