The highly-anticipated Creepshow holiday special from Showrunner and The Walking Dead-collaborator Greg Nicotero has finally arrived.

The hour long special titled 'Shapershifters Anonymous' follows Weston, a young man who experiences blackouts and believes he might be a murderer. Weston soon learns however, he is actually transforming as an unknowing shapeshifter.

The feature is based on a short story from J.A. Konrath about an anxious young man who suffers from a peculiar condition and finds solace in a support group of shapeshifting monsters.

The story becomes especially tense when the Weston and his new community of similar afflicted shapeshifters find themselves battling against "Santa Claws" and his team of killer Kris Kringles.

“The Spirit of Christmas is alive and well in true Creepshow fashion,” said showrunner Greg Nicotero. “Reimagining how we look at the holidays and Santa Claus with an outrageous ensemble cast, a myriad of creepy crawlies and a few thrills and chills shouldn’t be missed.”

'A Creepshow Holiday Special' is currently streaming on Shudder.
