Milk (1999)

Forty-five-year-old Adrian has been living with his mother Lucy and running their Wiltshire dairy farm all his adult life. When Lucy unexpectedly dies of a heart attack, a rogue's gallery of family members show up at the farm to argue over the execution of Ruth's will. The one object that everyone seems to want, and several people try to steal, is Ruth's valuable Modigliani painting. In the midst of all this confusion over Ruth's death, a mysterious visitor named Ilaria inserts herself onto the scene and has a surprising effect on those gathered.
