At the ASPCA headquarters, Special Agent Joann Sandano is bringing in an injured iguana for examination. The iguana's owner suffers from schizophrenia, and not only has the animal been neglected, it is suffering from several fractures. This animal will need intensive care in order to regain its health. Special Agents Mike Geller and Paul Lai have been called out to Staten Island where a neighbor has reported a dead dog in a back yard. They're wary because neighbors have reported recent police activity at the house in question. The house appears to be abandoned, except for another dog trapped in the garage. The police will have to get involved if the dog inside is to be saved.
