A man and a remarkable Alsatian/German Shepherd dog make surprising crime stoppers in this dramatic action/adventure series.
The show is about the life of a special breed of cop - Canine Officer Hank Katts; a strong, self-made survivor from immigrant stock who has fought his way up from a tough steel mill town - and his canine partner who fight crime and the forces of evil.
Rinnie's keen instincts, loyalty and courage help Hank catch burglars, raid drug dens, defuse time bombs, find lost children and protect the weak from muggers.
It also shows the life of Hank’s nephew, Steve, through the death of his mother and his adoption by Officer Katts.
