On a quiet afternoon in the park, four-year-old Joey plays in the sandbox, when a stranger approaches looking for his puppy. While Joey's mom, Crystal, talks on her cell phone, the stranger convinces the child to help search. By the time Crystal turns around, her son has disappeared. Yet her reaction is odd, not what one would expect from a distraught mother. Is Crystal somehow involved in her son's abduction?
Meanwhile, on a ranch outside Houston, Texas Ranger Sarah Armstrong assesses a symbol left on the hide of a slaughtered longhorn, a figure that dates back to a forgotten era of sugarcane plantations and slavery. Soon other prizewinning bulls are butchered on the outskirts of the city, each bearing a similar drawing.
The investigations converge at the same time a catastrophic hurricane looms in the Gulf. Finally, as dangerous winds and torrential rains pummel the city, Sarah is forced to risk her life to save Joey.
