Imagine yourself as an uncanny mercenary. Yes, you shoot, but rather pictures, not people. And now imagine that you were sent into the middle of Mezoamerican nowhere by a rather annoying hyperactive biologist friend of yours who's main goal is to have some decent photos of the fish you've never heard of. Seems like a couple of another well-paid days, fortunately without any newlyweds. And it is - until you find out that someone was there before you. Much before - about 500 years.
