It involved a mother with two photosensitive children. They stayed in a house where everyone else was dead, and not until the end of the movie did they discover through death photographs of everyone else in the house and themselves that not only was everyone else dead, but they were, too, and the members of the household were attempting to show it by exposing the children to sunlight. One particular scene involved the mother holding a gun and opening the door to the piano room while music was playing, but nobody was inside the room.
