In this exploration of how Class B dog dealers frequently violate the law by illicitly selling 42,000 canines to veterinary schools and research laboratories ever year, documentary filmmakers Tom Simon and Sarah Teale conduct an undercover investigation into the Martin Creek Kennel by the animal rights organization Last Chance for Animals. Though Class B dealers are required to treat their dogs humanely and purchase them only when the seller displays all appropriate documentation due to the fact that they operate under the jurisdiction of the Department of Agriculture, dealers frequently ignore the regulations and have been known to purchase animals that are either strays or stolen pets. Martin Creek Kennel was once one of the largest Class B dealers in the United States, but when a young man named "Pete" landed an entry-level job at Martin Creek hosing out kennels and wore a hidden camera to work, the images of abuse, disease, suffering, and injury that he captured would prompt federal authorities to close the facility in 2005 and land owner C.C. Baird in court. With this release, Simon and Teale attempt to educate viewers as to the heartbreaking violations by Class B dealers that continue to go unsighted year after year.
