A man in a jump/flight suit-ish uniform waits many stories up in a building, looking out an expansive window at the view. A woman also in uniform enters. They kiss passionately and then take the long way down and leave the building. They are barely out of the building when it explodes. Everything around them starts disintegrating. They make their way out of the city and travel cross-country. After several days - tired, hungry, clothes now ragged - they come to the back door of a small cottage after walking through its back fields. Although they were looking only for a bit of food before moving on, the family takes them in.
Cut to some time later. The village is celebrating something or other. The couple looks back to the city from whence they came - which is still apocalypsing itself - and reflect upon their long journey and how the people back there can't see past their petty differences and seem intent on destroying themselves.
