A murder spins around a rock band. Elsewhere, Neely becomes Grace's next-door neighbor as Earl tries to pull her through punishing drug withdrawal. And Rhetta focuses on reconciling with her husband.

Grace struggles with the burden being placed on her, especially after the family members of a dead rodeo rider bring his body to Grace's house, hopeful that the "Angel Cop" will be able to find out how he died. Meanwhile, Capt. Perry braces for a significant life change; and Grace's brother Father John teaches the art of good communication to Rhetta and Ronnie.
