It’s Christmas, the time of year when large companies spend thousands of hours and dollars trying to figure out what the most profitable toy for children will be. However, Barney, a 12-year-old boy, has beaten these companies to it after searching through letters to Santa while in the confines of a mailbox. Now, he has organized a heist that no other child has ever pulled off before. His plan: to sneak into Mr. Helston’s department store, spend the night, and be the first person in line to buy all the Crabby Mousie dolls available. Little does Barney know, ambitious plans such as his never turn out as expected.
