He seems bent on sabotaging his relationship with Valerie Gannon (Neve Campbell). He's in a ratings war with his former protégé, Gareth Whitley (Skylar Astin), who has rebranded himself as the kinder, gentler voice of the right wing. He's embroiled in a public spat with a powerful senator (Judith Light). He's in danger of fading into irrelevance.When Lionel's sixteen-year-old niece Tess (Taylor Russell) shows up seeking his help with a family crisis, Lionel must confront the complicated family he's long since left behind. In Tess, Lionel has finally met his match: a smart, determined, brazenly honest sparring partner. Tess is facing her own dilemma, a stark choice between supporting her troubled mother (Tina Benko) or embarking on a lifechanging opportunity she's worked so hard to earn. As this unexpected bond develops, and his career crisis reaches a breaking point, Lionel must decide whether to rethink the power of his words and his legacy. Will he open himself up to a new kind of responsibility and connection? Or will he stay his fiery course, burning anyone who gets too close?
