The new series continues with Thackery now escaped from rehab and returning to the hospital, although he has trouble convincing the hospital board of his sobriety, naturally enough. They are even more taken aback when he announces he wants to perform research into drug addiction, rather than returning to work as a surgeon. Meanwhile, after making an unsettling discovery, Cornelia decides to do some digging, but is forced into making a deal with Cleary in return for his help. Elsewhere, Lucy gets a surprise visitor, and Edwards seeks help for his vision problems.
