The first footage from The Good Wife spinoff series, The Good Fight, is here -- and it looks like things are about to get brutal.

On Sunday afternoon, CBS premiered the 30-second teaser touting the anticipated drama ahead of its broadcast television debut during the winter finale of Madam Secretary.

"Practicing the law, you don't go on instinct," Diane Lockhart (Christine Baranski) opens in dramatic voiceover. "We wait and listen and watch. Eventually, everyone reveals themselves."

A montage of all the key players -- some returning and some new -- gives a glimpse into the intriguing drama that will consume the lawyers of The Good Fight.

The hourlong spinoff, which picks up one year after the events of the series finale of The Good Wife, an enormous financial scam has destroyed the reputation of a young lawyer, Maia Rindell (Rose Leslie), while simultaneously wiping out her mentor and godmother Diane Lockhart’s savings. Forced out of Lockhart & Lee, they join Lucca Quinn (Cush Jumbo) at one of Chicago’s preeminent law firms.

Some standout moments from the teaser include Maia in bed with another woman, a distraught Maia walking briskly through the halls of a law firm before breaking down in the bathroom, and a naked couple watching the news on TV.

"Things will get nasty," the promo promises.

If the teaser is any indication, Diane, Lucca and company aren't in Kansas anymore. Buckle up ladies, it's going to be a wild ride!

The series, from Good Wife creators Robert and Michelle King, also stars Delroy Lindo, Sarah Steele, Justin Bartha, Erica Tazel, Paul Guilfoyle and Bernadette Peters.

The Kings spoke to ET earlier this year about why it was a “no-brainer” to do a spinoff focused on Baranski’s character.

“[Diane Lockhart] was one of those characters, other than Will Gardner, that really seemed to pull audiences in,” Robert told ET at the time. “There’s a certain solidity to her and a certain sense that she commands a room , but also there’s a sensitivity beneath it. So it was a no-brainer to bring her onto the spinoff.”

The Good Fight
premieres Sunday, Feb. 19 on CBS before airing new episodes on CBS All Access.
