OWN has set a May premiere for its new original series Greenleaf. It will launch with a two-night premiere at 10 PM Tuesday, May 24 and 10 PM Wednesday, May 25, and will regularly air on Wednesdays at 10 PM for the remainder of its 13-episode first season.

The drama from Emmy-nominatedOWN 5 writer/producer Craig Wright (Lost, Six Feet Under) and Lionsgate TV, takes viewers into the unscrupulous world of the Greenleaf family and their sprawling Memphis megachurch, where scandalous secrets and lies are as numerous as the faithful. It centers on the journey of estranged daughter and disillusioned preacher Grace Greenleaf (Merle Dandridge) who has returned home after 20 years on the occasion of the mysterious death of her sister, Faith. As she reenters the world of Calvary Fellowship World Ministries, the Memphis megachurch run by her powerful parents Bishop James Greenleaf (Keith David) and Lady Mae Greenleaf (Lynn Whitfield), it becomes evident that things are not as virtuous as they seem and that the family’s outward display of faith hides sin and misdeeds. The series also features Oprah Winfrey as Mavis McReady, her first recurring scripted television role in two decades.

Desiree Ross, Kim Hawthorne, Deborah Joy Winans, Lamman Rucker, and Tye White also star. Clement Virgo (Book Of Negroes) directs.

Greenleaf is produced for OWN by Lionsgate Television. Executive producers are Oprah Winfrey, Craig Wright and Clement Virgo.
