Blending gritty drama and raw emotion, Heartland explores the sentiments on both the giving and receiving ends of the organ donation process and follows the highs and lows of life for the pioneering doctor at the center of it all. Each episode follows the parallel stories of patients waiting for organ transplants and the deaths of their would-be donors. Viewers are taken for an emotional ride from one bedside to the other, watching as family members make painful decisions to end life support and donate organs -- and, in another room, as desperate family members cling to hope that their loved one will be saved by someone else's death. It's impossible not to be touched by the sentiments of sadness -- and eventual joy -- within the patients' lives, as well as the relatable drama in Grant's personal relationships.

Emotional and heartfelt to the core, Heartland is sure to entertain, but it's definitely on the mature side. There's some sex (though nothing too graphic is shown), multiple references to Grant's past infidelities, occasional strong language, and a highly flawed character (a surgeon who smokes?) at the show's center. Plus, if your teens are squeamish about blood and body parts, the trauma and surgical scenes will be too much, and the strong emotions and gritty storylines can be upsetting for viewers of any age.
