After Vivian's mood transfusion fails, she urgently needs a heart transplant, but no matching donor is available. Yvonne, who holds the only artificial heart developed by Miss Grant's late father, faces a dilemma as the heart is crucial for her own survival. Mr. Quinn pleads with Miss Grant to give the heart to Vivian, insisting he will do whatever it takes to save her. Miss Grant hesitates but agrees to hand over the heart on three strict conditions, including Yvonne repaying the Grant family and attending an engagement ceremony in seven days. The episode ends with Yvonne forced to accept these demands to save Vivian’s life.
