Doctors take a Hippocratic Oath in which they promise to treat their patients and prevent diseases to the best of their ability, but they don't always live up to the oath -- especially celebrities' physicians. "Dr. Feelgood" looks at a number of situations in which celebrities were betrayed -- intentionally or not -- by entrusted their health to their physicians. Each episode takes a look at a different case, including the most infamous of recent times -- Dr. Conrad Murray and his potential role in the 2009 death of music icon Michael Jackson. Hourlong episodes of the series also explore the stories of model Anna Nicole Smith -- whose doctors were accused of conspiring to prescribe excess drugs before she overdosed -- and legendary singer Elvis Presley, whose doctor became a member of his entourage.
