Heartland stars Treat Williams (Everwood, Brothers & Sisters) as Nathaniel Grant, an intense, overworked organ transplant surgeon who battles the clock to save lives in the high-stakes world of transplant surgery. Dr. Grant’s devotion to his work takes a toll on his relationships, including the one with his ex-wife, played by Kari Matchett (Invasion), who works at the same hospital as the organ-recovery coordinator. The two must work past their personal clashes in order to save lives.

Heartland premieres Monday, June 18 at 10/9c on TNT.
