On Dec 3rd,1967, brothers Chris and Marius Barnard performed the first successful human heart transplant. While Chris embraced fame, Marius shied from it. In an exclusive interview filmed just before his passing in 2014, Marius finally agreed to telling his side of the story, but only if his daughter, filmmaker Naudene Leisegang, would be the one to tell it. This film reveals how fame affected the Barnard brotherly bond, settles the Hamilton Naki rumour, reveals a 50 year-old secret, and pays tribute to all involved in commemoration of the 50th anniversary. It also explores the future of cardiac surgery, and the strides still made today at Grootte Schuur hospital in Cape Town, South Africa.
