Director Matt Lambert explains:

Caspa feat. Keith Flint - 'WAR', follows more of the structure of a short film than traditional music video. It follows the lives of a group of friends who end up living on the outskirts of the city following the collapse of society. It chronicles their initial hedonistic response, to one of militance and anger after the death of one of their own. This calls them to return to the city and fight for survival and vengeance against an unknown threat.
