Life may be tough for the animals of Houston, but it’s about to get a lot tougher for those who mistreat them. When the Houston SPCA responds to a cry for help from a self-confessed animal hoarder they find themselves embroiled in one of the most extreme cases they've ever had to deal with. At a house just minutes from the Houston SPCA shelter more than sixty dogs have forced the hoarder from her own home. While she sleeps on the porch, the dogs have the run of the house and after years of neglect have turned feral and aggressive. At the rear of the property Investigator Maverick Wagner discovers the most heavily matted dog he's ever seen. Blind in one eye and all but deaf the dog is hanging on by a thread. Back at base the medical team fights to save her life while in Polk County Chief Investigator Charles Jantzen and the team have their hands full rescuing a herd of emaciated horses, including a wild mustang that refuses to come quietly.
