Lee Jong-suk, Yoon-a to Star in Upcoming Legal Drama Series

Lee Jong-suk and Yoon-a will star in cable channel tvN's upcoming drama series "Big Mouth" as a married couple.

Lee plays a lawyer who only wins 10 percent of his cases and is mockingly known as "Big Mouth."

After becoming embroiled in a murder case he is wrongly accused of being the biggest scammer in the country.

In a quest to prove his innocence, he stumbles onto conspiracies that reach the highest echelons of society.

Yoon-a plays a devoted nurse who supports her husband throughout his bar exams and legal training, and tries hard to clear his name.

Yoon-a has kept herself busy on both the big and small screen. Her new film "Miracle: Letters to the President" is set to hit theaters in time for Chuseok later this month.

"Big Mouth" will be aired later this year.
