Charlie Draper only took the job of finding the missing girl as favor. He approached it convinced that the hot desert sun had likely eliminated another unprepared hiker rather than a part of the Border Wars.
It didn't take long to realize his error. Then it became complicated. In less than a day, he discovers that drug cartel members shot her and threw her into a volcano vent. The resulting trail leads into Mexico, where his actions bring on the wrath of the cartel.
The bodies start to pile up with a vengeance as he and his helicopter-flying Apache friend attempt to rescue the young women and prevent the revenge-determined drug alliance from killing them all.
