Christmas is the most wonderful time of the year. A time of giving. A time of good cheer. But there's something strange in the eggnog this holiday season and it's all on display in Investigation Discovery's new one-hour special, NIGHTMARE CHRISTMAS. A naughty husband pays the price for opening his gifts five days early. Then, a Christmas Day caper sends a congregation into chaos when greedy Grinches make off with the church donations. And a ruthless thug gives Christmas re-gifting a macabre twist when he bestows his mother with a lavish but bloodstained robe, brutally unraveled off a recent victim. Using Investigation Discovery's signature recreations and interviews paired with all the classic elements of a retro Christmas special - including a holiday score, wintery motifs, and a narrator that sounds like Kris Kringle himself - NIGHTMARE CHRISTMAS premieres Thursday, December 13 at 10 PM E/P.
