Having spent years conducting missions in a jungle, ex-Special Forces leader Jim Ellison can do things most people can't. He has hyperactive senses -- the hearing of a dog and the night vision of a cat, among other things. As a police detective, he uses his super senses to fight crime. An anthropology student, Blair, who thinks Ellison is like the guardian Sentinels of ancient times, helps Ellison adjust and control his senses. Blair then joins Jim as a police observer and the two team up to fight crime in their village of Cascade.
