It's Christmas and the family is on a trip down to Mexico to see Grandma Ria, a vibrant active lady who loves life and the village kids. She has planned a wonderful Christmas for them, complete with presents and decorations. But the truck with all the Christmas surprises has been stolen by a couple of juvenile joy-riders. The truck gets hijacked by a couple of crooks, who plan to raid some ancient pyramids for gold and jewels. When Grandma finds out her Christmas toys have gone missing, she's off to get them back, with the help of Carlos, Reynaldo, Lisa, and Rubik, who likes Grandma but must hide from her to remain a secret. However, grandma is pretty sharp and after one too many amazing things happen, she's onto Rubik and the kids. When it looks like the crooks might get away and nothing else can be done, Grandma lets on that she knows the secret. Rubik is now free to use his amazing powers to save Christmas and make a new friend.
