When Rufus (Malcolm Barrett) and Jiya (Claudia Doumit) add a fourth seat to the Lifeboat, for the first time ever, Connor Mason (Paterson Joseph) joins the team as they travel back to the dusty backroads and smoky juke joints of the Depression-era South to rescue the life and legacy of Robert Johnson (guest star Kamahl Naiqui) -- King of the Delta Blues, Godfather of Rock n' Roll and a man who, legend has it, bought his musical genius from the Devil for the price of his soul.

Meanwhile, Agent Christopher (Sakina Jaffrey) keeps Wyatt (Matt Lanter) in the present to execute a dangerous raid on Rittenhouse headquarters.
