When another Mega Shark returns from the depths of the sea, world militaries go on high alert. Ocean traffic grinds to a standstill as everyone lives in fear of the insatiable beast. Out of options, the US government unleashes the top secret Mecha Shark project -- a mechanical shark built to have the same exact characteristics as Mega. A pair of scientists pilot the mechanical creature as they fight Mega in a pitched battle to save the planet. But when faulty mechanics cause the Mecha to go after humans, the scientists must somehow guide Mega to Mecha in hopes that the two titans will kill each other - or risk untold worldwide destruction.

With the threat of having to close her father's candy store, Wendy and her six-year-old daughter Grace travel to the big city in hopes of making extra holiday cash to save the store. When she's offered a job in the toy department of Wolmans, the city's biggest department store, Wendy can't wait! Her excitement doesn't last long when the store's manager, Teanna, destroys the Christmas spirit throughout the store and replaces Santa with a hunky male underwear model surrounded by elfin "babes." What Teanna is unaware of is that she has in fact sacked the real Santa. Unaware of his real "Santa" status, Wendy reaches out to the old man but it seems even he has given up hope. With her daughter losing faith in the holiday, Wendy realizes she must bring the true meaning of Christmas back to Wolmans before it is too late.
