Kim Raver, of “24” and “Grey’s Anatomy” fame, will star in ABC drama pilot “The Advocate.”

Raver plays tough-as-nails business woman Francis “Frankie” Reese. After a dangerous misdiagnosis, her character experiences first-hand the hazards of the U.S. health-care system. She leaves her successful career behind unexpectedly after the medical scare to become an advocate for those lost in the same ever-changing system.

Written by Sheldon Turner and directed by Michael M. Robin, “The Advocate” was inspired by the real story of former talent agent Byrdie Lifson-Pompan, who collaborated with doctor and health education specialist Valerie Ulene to launch a health-care consulting firm.

Turner and Jennifer Klein are exec producing, with Lifson-Pompan and Ulene serving as consulting producers.

Raver recently reprised her role as Audrey Boudreau in “24: Live Another Day.”
