Putting other people before themselves is a way of life for the Britt family. But during a time of global war and disease, the members of the family feel the strain especially hard.

Travis Britt served in a medical unit during the American Civil War. Now Curt, Clay, Noah, and James follow in their grandfather's footsteps and volunteer for service in a medical unit serving the allied forces during the war to end all wars. Two more grandsons, Drs. William and Edison Stewart, are stretched thin. One doctor cares for injured troops returning from France, while the other battles the deadly Spanish flu. Both have their own personal struggles and their father, old Dr. Thomas Stewart, must step forward to help during a time of crisis.

In the town of Harris, gossip is a way of life, and secrets bring out the worst in people. Brothers Luke, Cleve, and Reid Britt face a conspiracy as they work to protect the innocent from greedy, vengeful, and manipulative neighbors. But the allied nations also hold secrets. When Cleve and William discover one that endangers the American people, and those in Harris, Cleve must convince William to keep quiet.

Travis, now in his eighties, follows his memories back to the mountains he loved in his youth, only to discover a renewed passion for life and a fresh love for his children.

As they have always done, the Britt family takes care of each other. And they all wait to find out what sacrifices the family must now make.
