It is 1910, in Dorset. From a time before memory, De'Ath women have been herbalists, but now there is a doctor in the town. Jane De'Ath feels her way of life leaching away as science takes hold and townspeople begin to question the old ways. 

Then her only child becomes mortally ill. Is the doctor the only one who can save her daughter's life?
