Charles Stiles sends in Mystery Diners Jamie and Brooke to investigate. They uncover serious problems with Chris, the manager at The Stillery and Lacey, a female prep cook at Nashville Street Tacos involved in a scam. Chris is obviously running a rental scam for a self-help group in an apartment (under an assumed name on a rental website) that Steve owns when he's away and later a party secretly booked by Charles' private investigator Kimberly for Jamie who brought his cat over where Steve is allergic to cats. In addition, Lacey is seen upstairs cleaning the bathroom and taking out the trash before the next party arrives in order to suppress any suspicions. During the confrontation, Chris tries to convince Steve that he was trying to help bring in extra cash, but Steve doesn't believe him. Steve fires him and Lacey. The narrator revealed that Chris and Lacey have moved on to new employment. No self-help group meetings are ever held in Steve's apartment. Steve was partially inspired to rent out his apartment as long as the tenants follow his house rules.

Rose Melillo and Tom Kiermaier, the owners of Belcourt Taps in Nashville, Tennessee, contacts Charles Stiles for help after hearing rumors that their songwriting contest is rigged. 80s pop star Tiffany Darwish goes undercover as a Mystery Diner to investigate. The Mystery Diners show Rose and Tom that they have a right to be concerned thanks to the bartender Lee and the sound engineer Benjamin. Lee had been sabotaging the singers with free alcohol and getting them drunk so they can't perform properly and also setting off a blender to drown out the sound of their singing. Benjamin was seen messing around with the stage and sound so the other performers who weren't so intoxicated couldn't perform well. On top of it, they're having contest performers sing songs written by Lee and rigging the votes so they can win, all confirmed by Charles' private investigator Angela who also revealed that Benjamin owns his own recording company. This leads up to a singer named Paige winning the contest with a song from Lee that contained lyrics from her phone. When Rose and Tom confront Lee, Benjamin, and Paige, the two men tried to claim they were doing their jobs and the stage problems were legit. Rose and Tom don't believe this, pointing out they saw that both men were doing. When Charles asks Paige if she wrote the song she sang, Paige doesn't answer and starts to silently cry which Charles takes as a "no." Rose and Tom fire Lee and Benjamin while also telling Paige that she is disqualified from the contest. Rose and Tom then thank Charles for his help. The narrator revealed that Lee and Benjamin have ended their collaboration. Outside of Paige, the other three singers who won previous contests with Lee's songs were also disqualified. The singing contest is no longer being rigged at Belcourt Taps.
