True crime podcaster Trinity Scott is chasing breakout success, and her brand-new serial may get her there. Her subject is Clayton Jay Pelley. More than two decades ago, the respected family man and guidance counselor confessed to the brutal murder of teenage student Leena Rai. But why he killed her has always been a mystery.

In a series of exclusive interviews from prison, Clayton discloses to Trinity the truth about what happened that night beneath Devil's Bridge. It's not what anyone in the Pacific Northwest town of Twin Falls expects. Clayton says he didn't do it. Was he lying then? Or now?

As her listeners increase and ratings skyrocket, Trinity is missing a key player in the story: Rachel Walczak, the retired detective who exposed Pelley's twisted urges and put him behind bars. She's not interested in playing Clayton's game--until Trinity digs deeper and the podcast's reverb widens. Then Rachel begins to question everything she thinks she knows about the past.

With each of Clayton's teasing reveals, one thing is clear: he's not the only one in Twin Falls with a secret.
