Rosewood and Villa must follow a trail of clues left for Rosie, before another victim falls prey. As things heat up between Villa and Mike, Villa escapes by throwing herself deeper into the case, which inevitably pushes her closer to Rosewood. Meanwhile, Donna intervenes when Pippy decides to give TMI’s absentee mother a piece of her mind. Plus, the Chief position is Hornstock’s, if he is willing to pay a stiff price.

Rosie insists on celebrating his and Villa's nine-and-a-half month anniversary as partners, which lands them in the middle of a case involving none other than Julius "Joo-Joo" Beeman, their confidential informant. But, this time, Joo-Joo is the prime suspect. As Rosie and Villa work to uncover the truth, even if it means putting Joo-Joo away for life, they discover a whole new side of him they never saw coming. Meanwhile, Villa's choice for her new home has Rosie worried about the new path she's on, Pippy and TMI struggle to balance old friends and family, and Hornstock has trouble reading signals from the new, badass, female chief of police.
