NBC's upcoming hospital drama Heartbeat will turn the real life of cardiothoracic surgeon Dr. Kathy Magliato into a heart-racing hospital drama.

Melissa George plays Magliato's television alter ego Dr. Alex Panttiere, a maverick surgeon who isn't afraid of pursuingbig risks for big rewards. Her rock-star style in the operating room has to be balanced with her equally fast-paced love life. (Imagine cracking a chest open in the morning to come home to your ex-husband and two kids, an ex-boyfriend turned co-worker and your new boyfriend. It sounds like a roller coaster just talking about it!)

In the below exclusive first look, the cast and Magliato break down what the show is all about and how they managed to turn this real-life rebel's story into a television drama.

Heartbeat premieres March 23 at 9/8c on NBC.
