Watch The Emotional Moment This Mom Hears Her Dead Son’s Heartbeat.

When Heather Clark's 7-month-old son Lukas died unexpectedly, she was absolutely heartbroken. Despite her tremendous feeling of loss, Clark decided that Lukas' death would not be in vain: She would donate his organs so that other families would have a chance to avoid the same crushing loss she'd felt.

Meanwhile, in another part of the world, a 4-year-old named Jordan Drake desperately needed a heart due to a congenital defect. After undergoing six surgeries, she finally received the donor heart she needed to survive: It was Lukas Clark's.

In the video below, the mothers of the two children meet for the first time. Heather Clark finally gets to hear her son's heart beat again, only this time, inside of a little girl whose life he saved. Warning: You're going to want to get the tissues for this one.
