There is a heatwave across Europe.

Goose and his three sisters gather at the family's house by Lake Orta in Piedmont, Italy.

Their father, a famous artist, has recently remarried a much younger woman and decamped to Italy to finish his masterpiece. Now he is dead and there is no sign of a painting.
