Sunday's installment of "The Good Wife" will be dramatic and intense as Alicia Florrick (Julianna Marguilies) engages in a legal battle with a stubborn judge and gets romantic with her hunky independent investigator, Jason (Jeffrey Dean Morgan).

A preview of the upcoming episode, which is entitled "Judged," reveals that Alicia will file a lawsuit against a sitting judge in order to defend an innocent man who was wrongfully convicted.

The teaser video also features Alicia and Jason getting hot and steamy in an elevator.

Meanwhile, the synopsis of the next episode suggests that Alicia will go to great lengths to defend a former bond client who should not have been sent to prison.

"Alicia argues against Judge Schakowsky (Christopher McDonald) when she learns that a former bond court client was wrongfully imprisoned. Also, Diane assists the student editor of a college newspaper when the school threatens to fire her for writing a politically charged article," it reads, according to Carter Matt.

In addition, there is also a chance that Alicia and Luca Quinn (Cush Dumbo) will take Cary's (Matt Czuchry) offer and join Lockhart, Agos and Lee. In turn, a partnership could help both law firms, which are struggling to boost their appeal to clients, notes Carter Matt.

Meanwhile, Marguilies dropped a major bombshell earlier this month at the Casting Society of America's third annual Artios Awards, suggesting that she will no longer be part of the CBS series starting in April. While giving a speech praising the outgoing executive producers of "The Good Wife," Robert and Michelle King, the actress joked that she will be out of work in a few months.

"I surprised Robert and Michelle tonight. They didn't know I was going to be here. They think I'm here for them, but I'm unemployed come April, and I think you haven't seen me in a while - at least not in person - so I thought I should show up," she said Thursday night at the award show, which honored the showrunners, reports The Los Angeles Times.

Episode 13 of Season 7 of "The Good Wife," "Judged" will air Sunday, Jan. 31 at 9 p.m. ET on CBS.
