A 43-year-old woman lives with her father in a fishing village in the north of Norway. Together they run a factory that has been in the family’s possession for generations. The childless and unmarried woman lives in the basement of the factory, while her father resides upstairs. The building is dilapidated after years without maintenance and with progressively violent storms. The rising seas makes water seep into the basement, and mold and rot to spread.
When the father – suddenly and unexpectedly – marries a thirty-year-younger woman, the relationship between him and his daughter comes to a head. As witnesses to his new lust, reckless money spending and dream of a new heir, the daughter slowly starts descending into the blue.
