In the Texas bayous, a local homicide detective teams up with a cop from New York City to investigate a series of unsolved murders.

Souder, a homicide detective in a small Texan town, and his partner, transplanted New York City cop Detective Heigh, track a sadistic serial killer dumping his victims' mutilated bodies in a nearby marsh locals call 'The Killing Fields'. Though the swampland crime scenes are outside their jurisdiction, Detective Heigh is unable to turn his back on solving the gruesome murders. Despite his partner's warnings, he sets out to investigate the crimes. Before long, the killer changes the game and begins hunting the detectives, teasing them with possible clues at the crime scenes while always remaining one step ahead. When familiar local girl Ann goes missing, the detectives find themselves racing against time to catch the killer and save the young girl's life.

In Texas City, Texas, detectives Brian Heigh and Mike Souder are investigating a series of murders of women. When they leave the crime scene where a body was found, Brian brings the girl Ann Sliger that is on probation to the house of her dysfunctional family and delivers the neglected Ann to her careless mother. Then they are called by Detective Pam Stall, who is Mike's ex-wife, to help her to investigating a case of missing woman, but the case is outside their jurisdiction. However, they join Pam in her investigation while the family man Brian tries to help Ann and protect the girl against the abusive friends of her mother. Mike follows a clue that leads to two local criminals while Brian follows a different line of investigation and finds that the bodies were dumped in an area called "The Killing Fields". When Ann is kidnapped by the serial-killer, Brian seeks her out alone in the dangerous land.—Claudio Carvalho, Rio de Janeiro, Brazil
