SEASON 4, EPISODE 411 - When Jeffries' former partner shares new information about the 2000 murder of a male singer, the case is reopened, requiring Rush and a reluctant Scotty to travel to Knoxville, Tennessee, and delve into the world of country music. The victim was caught between women from two very different worlds--one Southern, one Northern--and the detectives must untangle a web of love, destruction and booze. At first, Rush and Scotty believe the murder resulted from a lovers' triangle, but they soon find out it had nothing to do with love and everything to do with music. Original songs by multiple Grammy Award and Country Music Award winner Tim Mcgraw are featured throughout the episode.
