Devil's Revenge plot
"Welcome to Hell"
John Brock is an archaeologist who returns from an expedition to the caverns of rural Kentucky after unsuccessfully trying to find a mysterious relic that his family has been searching for for generations. Upon his return, John has visions of a bird-like creature from folklore. He soon discovers that the relic is indeed in the cave he was researching and that this cave is also a portal to hell and a place of worship of the occult. The only way to stop the increasingly realistic visions is to return to the cave with his family, find the relic and destroy it once and for all.
