Diane (Christine Baranski) will be featured in a major storyline in Sunday's episode of "The Good Wife" after she is forced to work on a case about abortion that goes against her personal beliefs.

Meanwhile, Alicia (Julianna Margulies) and her partner Lucca (Cush Jumbo) will go to great lengths to build their clientele in order to save their floundering law firm.

"Diane is personally conflicted when she is forced to argue a heated case between pro-choice and pro-life advocates in order to retain an important client, represented by attorney Ethan Carver (Peter Gallagher). Also, Alicia and Lucca are desperate for new business and attempt to poach clients from Louis Canning (Michael J. Fox)," reads the synopsis, according to Carter Matt.

A preview for the upcoming episode, which is titled "Restraint," shows Diane getting into a heated exchange with Judge Ben Markovski when she requests "to file a motion for substitution of judge" before the court.

The surprised judge replies, asking, "Are you asking me to remove myself?" before he sharply denies her request.

In another part of the trailer, Eli Good (Alan Cumming) appears to be getting romantic with billionaire donor Courtney Page, played by guest star Vanessa Williams

The series also released a sneak peek video where Alicia's daughter, Grace, is seen offering her mother assistance in finding clients in order to help her revivie her law firm.

During an interview with E! News, actress Makenzie Vega revealed that her character has evolved from a whinny little girl to a more supportive daughter in Season 7.

"This season she's really able to support Alicia more and I think in doing so, I think everyone's probably to like her more-I like her more," she said.

"Grace does have a new role this season. Playing that has been absolutely incredible," Vega added. "It's fun getting to actually have an impact on what's going on in Alicia's life and actually being able to help out."

In another video teaser, Diane tries to convince Jason to work for her firm full time, arguing that he would earn more money. However, Jason turns the offer down, telling her "money is not everything."

In a third video, Eli stops by Alicia's home to tell her that Courtney has agreed to hire her firm to represent her.

Episode 8 of Season 7 of "The Good Wife," "Restriant," airs on Sunday, Nov. 22 at 9 p.m. ET on CBS.
