This shot starts of by showing us a fairly quiet desert like area which has a very peaceful tone to start of. That peace is then broken by a speeding camper van. This instantly shows us the chaos happening in this scene and foreshadows the the series as a whole from peace to chaos, from chemistry teacher to drug lord. The camper van can also show us the importance of family throughout the series as at first it is Walter’s, the main character, reason for getting into the meth business.
