When Jeffries' former partner shares new information regarding a case from 2000 involving the murder of a male singer, the case is re-opened and requires Lilly and a reluctant Scotty to travel down south.

Lilly and the team delve into the world of country music when they travel to Knoxville, Tennessee to investigate the case and Scotty is less than thrilled to be joining, as he is not a big fan of country music or the South. The victim, Truck, was caught between women from two very different worlds, one Southern, one Northern, which leads the detectives through a tangled web of love, destruction, booze and good old country music. At first, Lilly and Scotty believe it was a lover's triangle gone bad, however, they soon find out it had nothing to do with love and everything to do with the music.
