It's a story we've followed for the past 14 years: A little boy named Tommy Schomaker born with essentially half of a heart.
A lifesaving transplant. The chance to meet his heart donor's family. The chance to live.
Then, a day Tommy's family feared they would never see: his high school graduation, and a very special guest by his side.
This is the story of two families sharing one heart.
