Sheriff Rockwell teams up with the new sheriff of York County, a young woman, to solve a murder that happened on the county line.

When a not-so-popular lawyer is killed on the county line, Maksville County Sheriff Alden Rockwell must reluctantly work with the newly elected Sheriff Jo Porter of the neighboring York county. Her "big city" methods clash with his "old school" ways, but when the murderer continues to strike, they must learn to set aside their differences and work together in order to stop the killer.
