He then begins to walk back to town, but comes across Jennifer in the stuck pickup truck. He helps free the truck, then warns his wife that as the only uninfected person she needs to leave. However, he intends to return to town to help as best he can. At the same time, the film shows two men loading a biplane with barrels of liquid.
