Having survived sinister scarecrows and the malevolent smiling man in Small Spaces, newly minted best friends Ollie, Coco, and Brian are ready to spend a relaxing winter break skiing together with their parents at Mount Hemlock Resort. But when a snowstorm sets in, causing the power to flicker out and the cold to creep closer and closer, the three are forced to settle for hot chocolate and board games by the fire. Ollie, Coco, and Brian are determined to make the best of being snowed in, but odd things keep happening. Coco is convinced she has seen a ghost, and Ollie is having nightmares about frostbitten girls pleading for help. Then Mr. Voland, a mysterious ghost hunter, arrives in the midst of the storm to investigate the hauntings at Hemlock Lodge. Ollie, Coco, and Brian want to trust him, but Ollie's watch, which once saved them from the smiling man, has a new cautionary message: BEWARE. With Mr. Voland's help, Ollie, Coco, and Brian reach out to the dead voices at Mount Hemlock. Maybe the ghosts need their help -- or maybe not all ghosts can or should be trusted.
