When a man is found murdered at an elaborate holiday party complete with real snow and live reindeer, the CSI team is brought in to investigate.
At an elaborate private seasonal party complete with real snow and live reindeer, the Santa is fatally stabbed. The team finds he switches places, barely noticed, with host Ryan Bonham, whose pre-teen son Blake is the only witness of an intruder. Furthermore, the fake snows got mixed with a Mexican cartel's smuggled cocaine.—KGF Vissers
When a reindeer wanders though the Strip with blood on its fur and hooves, the CSI find a Christmas decorated house with snow and a dead Santa Claus. He is identified as Brad Fante, an employee of Bonham Realty. David Phillips finds five stabs on his back and that the sleigh ran over his legs. Ryan Bonham tells Russell that his company had a great year and he was hosting the Christmas party for his employees at home. Greg processes the reindeer that belongs to the company of Jayson Walt that organized the snow and the environment. When Nick sees the footage of the party, he finds that there was two Santa Claus. When they learn that Jayson was the other Santa Claus and who his brother is, the crime begins to be solved.—Claudio Carvalho, Rio de Janeiro, Brazil
