*Oprah Winfrey sits down with Oscar-winning actress Jane Fonda and her adopted African-American daughter Mary Williams for their first-ever interview together on “Oprah’s Next Chapter,” airing Sunday, April 7 at 9 p.m. ET/PT on OWN.

Williams grew up in Oakland as a member of the Black Panther Party, as chronicled in her recently released memoir The Lost Daughter. Williams was one of six children raised by a single mother after Mary’s father was sent to prison. At age 13, Mary was invited to attend the Laurel Springs Children’s Camp run by Jane Fonda and her then-husband, Tom Hayden. There, her bond with Jane grew strong. One year later, Jane invited Mary to live with her in Santa Monica, California.

On “Oprah’s Next Chapter,” mother and daughter tell Oprah how they met, and Williams shares what it was like becoming a part of Fonda’s Hollywood life. Fonda’s biological son Troy Garity, who starred in “Barbershop” and the Starz series “Boss,” also joins the conversation, discussing what it was like to have Williams come into their family.
