Driven to seek shelter from a snowy storm, the Mushi Master Ginko is drawn into a yearly mystery. A lone boy wanders off into the forest during the harshest part of every winter, only to be later found asleep and clutching spring’s blessings in his grasp, reawakening the very next season unharmed. But when Ginko unknowingly releases the mushi that is key to end the enchanted sleep, he must follow the boy into winter's hibernation. The traveler will reminisce how home can be so much more than where one slumbers.
