Mercy, a new medical drama with a unique point of view, portrays the lives of the staff at Mercy Hospital as seen through the eyes of those who know it best - its nurses. Nurse Veronica Callahan (Taylor Schilling, "Dark Matter") returns to Mercy from a military tour in Iraq - and she knows more about medicine than all of the residents combined. Together with fellow nurses Sonia Jimenez (Jamie Lee Kirchner, "Rescue Me") and Chloe Payne (Michelle Trachtenberg, "Gossip Girl"), Callahan navigates through the daily traumas and social landmines of life and love both inside the hospital and out in the real world.

James Tupper ("Men in Trees") as Dr. Chris Sands, a new doctor at the hospital who complicates Veronica's life; Diego Klattenhoff ("Supernatural") as Mike Callahan, Veronica's husband; and Guillermo Diaz ("Weeds") as Nurse Angel Lopez.
