Krampus Unleashed (2016)

In 1898, German outlaw Erik Klaus disappeared, leaving behind ominous warnings to those looking for the treasure he buried in the Arizona desert. Years later, a group of cowboys discovers the loot: "summoning stone" that releases Krampus when exposed to open flames. According to myth, Saint Nicholas left pieces of the stone in the shoes and stockings of his enemies, so that Krampus would kill them when the clothing was placed by a fire to dry. When the stone is dropped on a lantern, Krampus is summoned and proceeds to massacre the cowboys. As Cooper, the sole survivor, flees, the stone falls into a stream, and is lost.

Decades later, Will and Amber, along with their children Tommy and Fiona, travels to Arizona to spend Christmas with Amber's parents, Dale and Alice Henderson. Also present are Amber's environmentalist brother, David, his wife, Vivian, and their delinquent son, Troy. While gold panning in a creek near the house, Tommy finds the summoning stone. When Troy accidentally burns the stone with a lit cigarette, bringing forth Krampus. The creature runs amok, murdering a pair of Bigfoot hunters, as well as the boyfriend of a woman named Bonnie who lives nearby. Bonnie seeks aid from the Hendersons and uses their telephone to call 911.

As they wait for the police to arrive, Will, Dale, Alice and Amber are all slaughtered by Krampus. David, Vivian, Fiona, Troy, Tommy and Bonnie try to flee in a car, but it crashes, killing Vivian. David attacks Krampus to buy the others time to run away and is ripped to pieces. Bonnie, Fiona, Troy and Tommy make it to Cooper's trail who has spent his life studying Krampus ever since he survived it all those years ago. Cooper reveals that Krampus is summoned by fire, but can be banished back to Hell by earth.

Cooper, Bonnie, Fiona, Troy and Tommy lure Krampus into an abandoned mine shaft with the summoning stone, and Cooper sacrifices himself to collapse the cavern on Krampus with TNT while the others escape. In the morning, Bonnie, Tommy and Fiona and are found by Bonnie's ex-boyfriend, a state trooper named Dan. Troy, who had become separated from the others, is mauled by a baby Krampus that had hatched from the summoning stone.
