The trek is difficult for her, but she ultimately earns Sully's respect and gratitude after saving his life twice despite a broken wrist. Just as they confirm that the water is being polluted by a local mine owner whose mining process is dumping mercury into the stream, they are captured by his men. In the interim, worried townsfolk send out an inept posse to try to locate Sully and Dr. Mike. Olive backs Grace's new venture -- Grace's Cafe.

She must help Doc Eli face his past demons, before he can help her remove an ovarian cyst from Myra, in a technique he pioneered.

Matthew's sudden announcement that he wants to marry Ingrid causes upheaval in his relationship with Dr. Mike, who feels he's too young.
