Zoo (1999)

A dark comedy set in the fictitious tiny hamlet of Spraine. A big city private detective is hired to track down an animal serial killer gone awry. The town wanted to bury the story, keep the outsiders out. The police had to pin the crimes on somebody: three notorious bad boys are being falsely accused of brutally slaying the local farm animals. The detective gets drawn into the intricacies of this seemingly upstanding community, only to find out the true meaning of animal lovers... a bit more than he bargained for.
