Nick Fallin is a hotshot lawyer working at his father's ultrasuccessful Pittsburgh law firm. Unfortunately, the high life has gotten the best of Nick. Arrested for drug use, he's sentenced to do 1,500 hours of community service, somehow to be squeezed into his 24/7 cutthroat world of mergers, acquisitions and board meetings. Reluctantly, he's now The Guardian - a part-time child advocate at Legal Aid Services, where one case after another is an eye-opening instance of kids caught up in difficult circumstances.

Dr. Nathaniel Grant is a pioneering organ-transplant surgeon who takes risks that other doctors would not in order to save the lives of his patients. He works closely with his ex-wife, Kate Armstrong, an organ-donor coordinator with whom he has a volatile relationship. Grant's arrogance and willingness to perform risky procedures causes him to butt heads with the hospital administration. But his main focus is on his intense relationship with his job and his patients, often at the expense of his family.
