The Bow (2005)

"A girl who thought the sea was the whole world, became the whole world to an old man."

On a fishing boat at sea, a 60-year old man has been raising a girl since she was a child. It is agreed that they will get married on her 17th birthday. They live a quiet and secluded life, renting the boat to day fishermen and practicing strange divination rites. Their life changes when a teenage student comes aboard.
