Police comedy drama series about a strait-laced Canadian mountie and his pet wolf in Chicago. When Gerrard, Fraser's father's murderer, evades his police escort en route to testifying in front of the Grand Jury, Fraser soon finds himself embroiled in the manhunt. He and Ray's first port of call is the factory of a hardened arms dealer, Nash, against whom Gerrard is supposed to be giving evidence. However, further investigation convinces Vecchio and Fraser that Nash himself isn't the focus of the trial and reveals a massive web of police corruption extending right across the border.
