Shadow is not your typical lazy house dog. She works with her town’s police department, helping them find bad guys. Shadow has a very special, very sensitive nose that allows her to pick up the smell of any law breakers. After a person commits a crime, they start to stink. The worse the crime… the more stinky they become, at least to Shadow’s nose anyway. Since becoming a police pup, Shadow has aided in the capture of 99 criminals. She only has to find one more to reach her goal of “100 Bad Guys Behind Bars.” The next villain on her list to find won’t be as easy as the others though. His name is Captain Crime, and he is a very clever, sneaky, corrupt man. He has been avoiding arrest for a long time, causing a lot of harm to innocent people in Shadow’s town. She is determined to catch Captain Crime before he breaks any more laws.

Will Shadow be able to find Captain Crime, rid her town of his wrong doings, and reach her "100 Bad Guys Behind Bars" goal?
