The video starts with the view from the back seat looking over Paige's shoulder as she gets in and tries getting the old car started. She pumps the gas before turning the key to prime the carburetor. It takes some tries, so it's not starting right up is nothing unusual. The battery is getting weak and the dash lights are flashing slower and slower, so it's probably time to change the battery.
You're now watching from the open drivers door as she keeps working the process: pump the gas, turn the key and keeping pumping...but not too much. Come on...Come oonn....!!!!
