When a gunshot victim comes into Alan's ER, he jokes that this guy doesn't need a doctor, he needs a veterinarian. As he keeps working, though, the patient seems to be getting less hairy and less hurt. All except for the bullet wound that's now festering badly. Alan is shocked when his patient seems to miraculously heal as soon as he removes the bullet. He's even more shocked when the guy turns up at his house later to offer a very personal thank you.

Can he figure out Shiloh's secret before it's too late?
