With Christmas presents on the attack and carols of gunshots drowning out the bells, Sam & Max must storm the North Pole to bring down a less-than-jolly foe. Can the Freelance Police make sense of this Christmas conundrum in time to save the world's children from a holiday tainted by tears, turmoil, and Torture-Me-Elmer?
