Full Episode
So this guy is a cult leader, and he wants nothing more than to sacrifice a white guy. Now the story starts with Mark. In Mark's 21, he goes to college in Texas, and he eventually wants to go to med school. And one day in 1989, Mark and some of his college friends, they decide they're going to travel somewhere for spring break.
And Mark, he ends up going from Austin down to South Padre Island, and then to a little border town called Brownsville. Now in Brownsville, there's a bridge where people can literally walk across the border into Mexico, where there's this town where spring breakers will go and they party.
So Mark and his friends, they cross this bridge and they go to this town and they get drunk and they have a great time. The second night they're there, they go out again and they bar hop a couple of places and they drink all night and Mark talks to some girls, you know, normal spring break sh**. Then around 2 a.m. Mark and the guys they leave the bar to go back to their hotel.
So Mark and his friend they're walking along and it's pretty crowded and his friend stops to take a leak. So he goes down this alleyway while Mark is standing there waiting for him. And right then a red pickup truck pulls up. And the men inside they talk to Mark and they're like hey you want a ride? And Mark's like nah. But then boom some of the men grab him and they throw him into the truck.
But Mark, he ain't no punk. He ain't about to get kidnapped. And so they fight, and they struggle, and bam, he manages to break free, and he runs away, and he runs, and he runs, but then another car catches up to him, and they're with the guys in the red truck. And these guys, they aren't messing around, and they point a pew-pew right at him. And they're like, get in!
And so Mark does, and skrrt, they speed away. Sometime later, these cars arrive in the middle of nowhere at this remote ranch. Now this ranch is full of all these crazy people. And these aren't like the cartel you would assume would be out kidnapping drunk Americans. This is a cult. A crazy drug trafficking cult. And they apparently distribute a lot of Zaza out of this ranch.
And the leader of this cult is this guy, Adolfo. And Adolfo and his followers, they believe some crazy shit. They believe in magic, like the Harry Potter kind of magic where there's like curses and shit. And in order to keep their gang safe from police, they need to make some literal sacrifices. Sometimes these sacrifices include a small animal, but other times they sacrifice a human.
Now usually when they sacrifice a human, they capture an unalive like a rival gang member or some other drug smugglers. But this time, for whatever reason, Adolfo tells them they need to sacrifice a white boy. And that is when his cult members go out and they happen to find Mark and they kidnap him and they bring him back to their ranch.
So now, Mark is at this creepy farm, and they're still holding him at gunpoint, and they handcuff him, and they leave him in the back of this car. And about 12 hours later, they come get him. And they tell him he's gonna be fine, and they give him a little food to eat. Then, they take him, and they put him in this little storage shack.
