A childhood friendship-and Facebook-could save John Brannon's life. While on the brink of kidney failure, John reunites with an old friend who suddenly realizes that she has the ability to save him through organ transplantation. Meanwhile in the same hospital, 5-year-old Chealsey Melendez is diagnosed with stage-4 cancer. Doctors harvest her own stem cells and freeze them so they can be transplanted back into her marrow at a later date, all in a desperate attempt to save her life.
