In 2015, Crystal Moore encounters a slave in Dallas, Texas -- a slave held not by chains, but by threats her two girls held hostage in the jungles of Mexico will be killed if she escapes.

To naïve Crystal, it's clear. The children must be rescued first, or the mother will never escape.

Crystal would like to forget it, but her conscience will not let her.

She goes to Mexico and secures the help of mysterious Juan Grande. If she succeeds, mother and children will be free -- but Crystal will have two powerful and ruthless men, one in Texas and one in Mexico, who will want her dead.
