The goof item below may give away important plot points.
It is established in the film that it is the use of a contaminated washing up powder that has caused the women of the village to turn into zombies. The film also stipulates that only exposure to the washing up powder will cause infection. Based on this, how can Candy also turn into a zombie after having not been to the village before, nor using the washing up powder herself?
