Detective Lorrayne Lobato of the Denver Police, by orders of the Governor, is summoned to the case with the understanding from Copeland, Major Crimes Unit Supervisor, with the understanding that all her requests are to be filled. FBI agent Ron Jacksen would join her later in Del Norte. She is flown from Denver to Del Norte where the wailing is then heard near the river. She is torn between duty and superstition.
Westside of Del Norte, known as The Westé, Officer Blackman and Officer Shaffer are sent to investigate a haunting wail near the Rio Grande River which flows north of town. Shaffer is brutally torn to shreds, and Blackman overcome with fear and heart failure which eventually claim his life.
Sofia, a local resident who lives near the river has cursed Blackman and Shaffer who are involved in her grandson, Bobby's ( Weddo's) murder which was dismissed as a suicide.
Lobato calls Copeland requesting, Miranda, a transsexual psychic who worked with her on a previous case, to be brought to the valley. She believes in Miranda's abilities as she has seen them work before.
Miranda is infuriated when Denver police awaken her at 4 a.m. escorting her to Del Norte. She is not amused when she learns Lobato is behind it, and perplexed as she is aware of the legend as well. Sergeant Don Forest is there to meet her at the airport. She arrives by helicopter.
Forest and Officer Mathews are irritated with Miranda. Their attitudes toward her are obvious. Mathews is further irritated with Lobato in charge.
Lobato and Miranda visit crime locations where Miranda's psychic senses warn of a killer with no remorse, hooked on death. She senses it in each location with the exception when she and Lobato encounter a weeping, haunting vision clothed in Mexican, white lace in a mist along the river. From this vision Miranda senses no hostility, only a deep sadness-unlike what she feels at the scenes of bloodshed.
Bulldog, Luke, Billy and Wayne, four skinheads associated with White Justice, a white supremacist group out of the Colorado Springs area approximately 200 miles north of the valley, descend into Del Norte with hate filled hearts and violence on their minds. Upon entering the valley they brutalize a Hispanic woman and her elderly aunt in a robbery. Witnesses come forth with information.
Ida Vigil lives in east Del Norte near the river with her husband Officer Bob Vigil and their two small children Andrea and Edwardo. They are terrorized and brutalized by the skinheads when they make way into their home. Ida manages to flee with her children to a hiding place she knows near the river.
Bulldog and his buddies discover the hiding place in which Ida and the children are hiding. Unmercifully they are dragged out of the hiding place and beaten. Bulldog and his buddies are distracted when they see a mist coming down the river. Their laughter fills the night when they see the same girl in the vision Lobato and Miranda had seen. The girl lures them down the river into the darkness. They are later found when Ida's husband comes home and finds his wife and children gone, the house in shambles. Bulldog, Luke, Billy and Wayne are found paralyzed from the neck down and blind. They have also lost their sense of seeing, hearing and speaking. Doctors are unable to explain.
Lobato's anticipation grows with each victim and visions Miranda is having at each crime scene. Not even Forensics is able to find evidence. At each crime scene the only thing to be found are mangled bodies. She and Miranda set up camp in crime scenes in hopes of finding something, or something finding them.
FBI agent Ron Jacksen arrives certain to close the case within twenty-four hours. His mind is quickly changed the more he learns of the case. He is attracted to Miranda. He, Lobato and Miranda begin their quest.
Father Henry Luna has issues with Lobato's choices when he meets her, Jacksen and Miranda. He has strong opinions of Miranda and the likes of her. He resides on the other side of the river where Montoya was killed. He too, is lured to the river where he is torn to pieces and later found by Julia who works with him at the church. It is later learned Luna has dark skeletons in his closet-one being his molestation and affair with Sofia's grandson and knowing who killed him, yet refusing to speak up.
Boa, a local resident is missing, then found. All who know him are left puzzled with his white hair which had been previously been jet black. Boa has encountered the same weeping girl in Mexican, white lace that Lobato and Miranda have seen. They too, are left puzzled. He is hospitalized.
Officer Bob Vigil is kidnapped by eight members of White Justice who come to valley for vengeance of their sons' situation. He is bound while clan prepare for his death.
Miranda's senses warn her of the situation with Vigil, and convinces Lobato and Jacksen to follow her lead. They come across White Justice in their march of doom around Vigil. In the midst of a gun battle four White Justice members are killed and Miranda is wounded. Steve Miller, known as The Dragon escapes with three others and later found almost dead. He has nearly drowned. White Justice is an organization of many secrets and levels of intelligence.
Miller's wife Jan and their daughter Myrah, venture into town with attitudes. Myrah instantly takes a disliking to Miranda which leads to a physical confrontation. They are white supremacists as well.
On Miller's death bed he says things that make Lobato think. With what he says she sends out teams to investigate under the currents of the Rio Grande where they find peculiar, robotic demons put together by members of White Justice, which have caused the fatalities and havoc.
By force Mathews takes Lobato to the river and makes her step into the shallow waters where he knows one of their robots lies in wait for a victim. Lobato is nearly torn to shreds by this robot clothed in black, Mexican lace as were the two others placed in other areas of the Rio Grande.
Anthony, a sixteen year old Miranda befriends, leads them to where Mathews has Lobato. Following a confrontation with Mathews, Anthony crashes the police vehicle into the robot which has Lobato in its deadly grasp. Mathews is caught in the currents of the Rio Grande and drug to the depths of the river where he dies.
Boa escapes from the hospital. Miranda and Lobato have the same idea and meet where they initially found Boa and see the vision of a young, weeping girl in white Mexican lace. There Boa is found along with the vision. He vanishes into the mist with the haunting, ghostly girl, who gazes back over her shoulder through evil, red, piercing eyes. Lobato and Miranda are left questioning the legend.
