1874, East Texas. Two friends pursue the Posse, a group of sadistic human traffickers who have kidnapped five women. Along with an Indian scout, they race against time to find and free the women before the traffickers sell them to sex-slave buyers at the Mexican border.

A company of friends rises in the funicular to meet unforgettably New Year's Eve on the top of the mountain. The guys are already anticipating how they will cheerfully slide down to the beat of the chimes and explosions of fireworks. But the adventure turns into a real nightmare, when in the midst of the holiday a flimsy trailer gets stuck over the precipice.
