The Apple TV+ series "In With the Devil" is getting some new cast members. As reported by The Hollywood Reporter, Greg Kinnear and Sepideh Moafi have signed on to star in the upcoming drama alongside Taron Egerton, Paul Walter Hauser and Ray Liotta. The series tells the story of an inmate who is asked to "coax a confession out of a fellow inmate who's a suspected serial killer." Based on a book by James Keene and Hillel Levin, In With the Devil centers on Jimmy Keene (Egerton), the son of a Chicago cop who winds up in prison. A few months into his sentence, the lawyer who prosecuted his case approaches Jimmy with a deal: Coax a confession out of a fellow inmate who's a suspected serial killer and he can go free. The series will explore the intimate relationship between two prisoners and the lengths that people will go to in order to seek redemption — if true absolution is even possible.
