Lost alumna Maggie Grace is set as the female lead in CBS pilot Code Black, a medical drama written by Michael Seitzman and directed by David Semel. Based on Ryan McGarry’s feature documentary of the same name, the drama series — like the docu — is set in the busiest and most notorious ER in the nation. The show revolves around four residents who are getting their first taste of ER medicine and the medical staff who mentor, teach and terrify them.

Grace will play Leanne, the residency director in the ER, a force of nature and a force to be reckoned with. She joins previously cast Marcia Gay Harden and Melanie Kannakoda.

Grace, who co-stars in the Taken feature franchise, recently wrapped production on Showing Roots alongside Uzo Aduba and will soon be seen in the Nicholas Sparks romance The Choice for Lionsgate. She is repped by UTA, Zero Gravity Management and Jackoway Tyerman.
