Heather Cohen might not look like your standard PI - the bright red hair and tattoos certainly turn heads but when faced with a potentially innocent man in jail she makes it her mission to help prove her client Justin Williams's innocence. He was arrested after an altercation on a beach led to shots being fired. Will a new discovery about his past derail her investigation before it's gained traction? Meantime, elsewhere in Tennessee, an all-female team led by Nashville native Renee Brewer are tailing a suspected cheater. A high-octane chase leads them to a new address...

In Tennessee, as questions emerge about the standard of police work in Heather's murder case, she turns to forensics to try and prove her client's innocence. But with other charges on the table and witnesses that won't speak, can Heather do enough to convince the DA? Meanwhile, in Georgia, an alleged thief has turned up on Sheila McPhilamy's radar. Her client claims she's owed payback but without an address, the case stalls. Then Sheila stumbles upon his unusual side hustle and goes undercover with her team in the hope of following him home.

Georgia Bounty hunters Alex Haynes and Jon Dalman start their new life as private investigators tracking down a man alleged to have stalked bar manager Lauren. As their case widens, they uncover further revelations about their mark that leave their client reeling. Back in Nashville, a meeting with friends lands a cold case for Renee Brewer and her daughter Amy. They head to a rural town in search of Rachel Conger, who has been missing since 2008. Rumors and accusations are rife, and all eyes look toward a connection to a man acting strangely on horseback.

With multiple sources naming their suspect, Alex and Jon discover evidence that may have been missed. They hope DNA will reveal the identity of their killer. Elsewhere, Sheila investigates a car hit by a train for proof of a possible murder plot.
