The second episode of this gripping investigative series starts in the summer of 2012, with supersurgeon Macchiarini under pressure when problems start to arise. His pioneering transplant work seems at risk when he discovers faults with the new synthetic organs. Macchiarini still has faith in the procedure and plans new operations. This time it will no longer be fatally ill patients on whom he tries out his new methods, but patients whose condition is not life-threatening. Will Macchiarini succeed with his pioneering work?
