Based on Robyn Carr's novel series, the CW show - which is now streaming on Netflix - follows neurosurgeon Maggie (Morgan Kohan) as she finds herself in legal trouble and returns to her hometown in rural Nova Scotia to reconnect with her estranged father, Sully (Scott Patterson). Three seasons later, Maggie has set down roots in Sullivan's Crossing and found love with Cal (Chad Michael Murray).
