"The Good Fight" is starting to look like "Fifty Shades of Law."

"The Good Wife" spinoff -- starring Christine Baranski as Diane Lockhart, Cush Jumbo as Lucca Quinn, and "Game of Thrones" alum Rose Leslie joining the group as Diane's goddaughter Maia -- premieres February 19 on CBS before moving to the streaming service CBS All Access.

CBS just shared the first teaser, which includes this silky and ominous-sounding declaration from Diane: "Practicing law, you don't go on instinct. You listen and watch. Eventually, everyone reveals themself."

The mood of the teaser is dark and mysterious, with several steamy shots, like this is a sexy thriller rather than a continuation of "The Good Wife."

Here's the CBS synopsis:

"The Good Fight picks up one year after the events of the final broadcast episode of The Good Wife. In the new series, an enormous financial scam has destroyed the reputation of a young lawyer, Maia Rindell, while simultaneously wiping out her mentor and godmother Diane Lockhart's savings. Forced out of Lockhart & Lee, they join Lucca Quinn at one of Chicago's pre-eminent law firms.

The series, from "The Good Wife" creators Robert and Michelle King, stars Christine Baranski, Cush Jumbo, Rose Leslie, Delroy Lindo, Sarah Steele, Justin Bartha, Erica Tazel, Paul Guilfoyle and Bernadette Peters."

Watch the teaser:

Here's the official poster, making it clear that is a "nasty woman" series with three powerful leading ladies:

For what it's worth, TVLine reports that Rose Leslie's Maia is a lesbian with a steady girlfriend; it's only noteworthy because you rarely see that on network series, especially the conservative CBS. But this isn't really a CBS show, it's a CBS All Access show.
