Aurora Borealis (2007)

Duncan Shorter is charming and bright and has never met a job from which he couldn't be fired. His buddies are growing up and beginning lives of responsibility, but Duncan is still looking for that spark. It arrives from a most unexpected corner. Visiting his grandmother Ruth's new senior residence, Duncan jumps at the chance to become the building's handyman. It will keep him close to his grandfather Ronald, whose faculties are failing as quickly as the light of this Minnesota winter. When Ronald goes, Duncan realizes, he'll take with him the last shadow of Duncan's father, whose unresolved death years earlier still haunts him. And then there's Ronald's feisty home nurse, Kate, a restless spirit as free as Duncan is trapped. They soon find themselves drawn together in a relationship neither one wants but both of them need.
