The longest-running scripted original drama in the history of Showtime returns for Season 10 with “We Few, We Lucky Few, We Band of Gallaghers!,” which picks up the action six months after the Season 9 finale. Frank (William H. Macy) is exploiting his leg injury to hoard as many painkillers as possible, a gambit that eventually leads him to an old friend. Debbie (Emma Kenney), meanwhile, takes over as matriarch of the clan, buoyed by the $50,000 Fiona left to her. Cameron Monaghan and Jeremy Allen White also star.
