Believe in Christmas Magic

As a child, Richard believed in the magic of Christmas. Now, as a jaded adult desperate for work, he's acting as a store elf. The weight of life is proving too much for him to bear, and in an act of desperation, he sends a letter to Santa, briefly reviving the belief he once held.

However, Santa is real, and twin elves Ellis and Emery manage to capture the letter, showing it to their mate Bear, a polar shifter. Reading between the lines of the letter, Bear sets out with the twins and reindeer shifter Rudolph to save Richard. 

Can they reach him in time and teach him to believe in the magic of Christmas once more?
