Damian Lewis and Paul Giamatti return for the second season of Billions tonight where the former plays a shady billionaire hedge fund trader while Giamatti is the U.S. attorney looking to bring him down. Tonight's opening episode picks up in the aftermath of their previous confrontation after that neverending game of cat and mouse in season one. Chuck is currently facing a lot of scrutiny from his office and from the Attorney General while Axe weighs his options for retaliation. Also tonight, Wendy entertains an offer from a rival hedge fund manager and Lara intervenes in an emergency at her children's school.
