The stakes on "Billions" just keep getting higher.

Showtime announced the premiere date for Season 4 of the drama: Sunday, March 17. The network also unveiled the first teaser, which hints at a new war brewing in the financial and political circles of New York City.

But where the fighting used to be between Bobby Axelrod (Damian Lewis) vs. Chuck Rhoades (Paul Giamatti), now it seems the two enemies are now allies in a union brokered by Wendy Rhoades (Maggie Siff).

In Season 4, they will both duke it out with former proteges. For Bobby, it's Taylor Mason (Asia Kate Dillon), his onetime numbers genius who left Axe Capital to start their own firm. For Chuck, it's former right-hand man Bryan Connerty (Toby Leonard Moore), whose betrayal led to Chuck losing his job as U.S. Attorney.

"We now live in a universe split down the middle. You gotta pick sides," Bobby says in the teaser. And with Bobby and Chuck on the same side? Everybody else had better watch out.
