BILLY & MOLLY is an enthralling documentary about the unlike relationship between a retired older man who is living in retirement the lower half of the Arctic of the Shetland Islands, who is out in his boat one day and comes across a young orphaned river otter. Within days, Billy finds the hungry, out-of-her depth river otter who is out of her depth in the larger Shetland Islands and the rough sea water nearby. He begins to feed her and a bond ensues. Narrated by Billy & his wife, we see the Molly as she comes of age and learn to depend on Billy. Molly has tapped into a source of profound emotional attachment for this enchanting creature. He eventually builds Molly a house. Then one day, a male Otter comes calling and Molly disappears. Somewhat dismayed Billy learns to accept her disappearance, until one day she returns and in need of some fatherly support. There is never a false step in this emotionally involving documentary, which shows three distinct species interacting, all of them emotionally stirring. Molly is a compellingly sweet-natured creature, playful, charming, and Billy becomes the father he never quite managed to be in life. This is story shows how we connect deeply with the creatures that we encounter in life. Molly is pure joy and you can see the profound affect she has on Billy's life. But Billy's generosity is compelling, as is his wife's. You will not soon forget this lovely film. Kudos to National Geographic and their partners for creating something so pure and and heart-expanding.
