Nick Campos is a part-time agent for the CIA.
Well, he is affliated with the Agency, if unofficially, because of who he really is. We will get more on than in a minute.
Nick Campos is a former U.S. Army Ranger who, at age 40, was nearing the time to get out and it was bothering him because he had no idea what he might do - other than the cliche of buying a run-down bar and drinking himself to death or boring other people that way with his war stories - and he has a bunch. His career in the Rangers is looking downward as he is getting into more and more trouble with really penny-ante things like smuggling illegal cigars - all just to fight the boredom and worry about the futre.
There is one thing that will happen to definitely change his outlike, though:
He becomes Santa Claus.
Wow, talk about burying the lead! Yep, Nick Campos, hard drinkin', hard fightin', hard lovin' Nick Campos. He was outside his tent encampment in the desert of Iraq on Christmas Eve of 2018 taking a stroll - okay, he had just relieved himself - when he hears over a dune a moan, actually several of them. And animal snorts. He cannot stop his curiosity so he investigates and finds ... a sleigh. And some reindeer (in Iraq?). And an old fat man in a red suit. Said chubby fellow with the awesome white beard was dying of a heartattack and told Campos he was passing his powers onto him. And then the old fat man passed away and the sleigh took off, with Campos on it, and that is how Campos became Saint Nick.
Jump ahead one year and Campos is back active, having come to L.A. and locating and capturing three of the FBI's most wanted and pinpointing a fourth. That got him noticed. And then the CIA came calling, already having met the new Santa as the new Santa had intended.
The new Santa wants to use his new-found abilities for something more than just delivering presents or coal. When you have the incredible ability to know who had been naughty or nice - and when and where such activities took place - that makes you pretty useful to a lot of various organizations. When a person can do that for anyone - including high-level terrorists - one organization particularly intrigued is the CIA.
This is how Nick Campos, aka the new Santa Claus, joins with the Agency and some of his own friends and colleagues - did I mention Jack, the head Elf at the North Pole - to go find some really bad bad guys.
