Special Investigator AnneMarie Lucas and her undercover partner are following up on reports of a dog in Brooklyn seen with tape wrapped around its muzzle. After a tense surveillance operation, the ASPCA agents arrest a man on the street and discover the dog, King, is seriously wounded. Meanwhile, Special Investigator Paul Romano and Special Agent Joe Pentangelo are having a busy shift. They find two emaciated pit bull terriers in a back yard and on their way back to the base get a report of another pit bull in serious trouble. Special Investigator Lucas and her undercover partner go to the Centre for Animal Care and Control in Brooklyn, where they catch up with three abandoned puppies, found tied up in a yard. One had died at the scene, the others were very emaciated. It seems they had been so hungry they had picked at their brother's body.
