The Christmas holidays. What starts as a relaxing house party for two
families coming together to celebrate the festive season gradually turns
into a horrifying fight for survival as one by one the children mysteriously
fall ill and begin to turn against their parents with increasingly
disturbing consequences.
I found the Xmas party scene to be particularly gratuitous with the spatula spanking.
It certainly would have been, if the mom hadn't been dressed as a reindeer. This is actually a traditional Laplander Festivus ritual. Great research!
