In order to save his life, Andy tries a risky new procedure on his wife's partner who suffers from an aortic aneurysm.

When a woman's husband needs a new kidney, she contemplates beginning a "Daisy Chain"; which means she will donate a kidney to someone and they in turn will donate their kidney until the chain is completed with her husband getting his kidney. Andy is not sure he wants to support such an action and he is concerned that another patient is rejecting his recently transplanted heart.
