A young man secretly watches his beautiful neighbour through binoculars. When she leaves the building, he follows her into the street and even into a grocery store, buying milk just to have an excuse to be there. Later we see that his refrigerator is already full of milk. After he is injured in a car accident, he finds himself in a train carriage in a strange realm between life and death. There he meets an older man who explains the rules of this new world. He also encounters the woman he loves – someone with whom he can finally connect. Yet he longs to leave this place and return to his life.
