Two young hikers set out to look for Yeti one day, and with the help of a bird friend, they trek further and further into the woods, sending letters to coax the shy creature out of hiding. But as their trip goes on, the hikers find that they have not prepared very well, and though their morale is high, food supplies are low, the forest is getting darker, and a snowstorm looms. Luckily Yeti is a friend they can rely on, and though he's not ready to come out of hiding, he sneakily finds a way to get the hikers exactly what they need when they need it.
