How a village in Senegal is using solar energy to bring itself into the modern age

In a remote village in Senegal, a woman is using solar energy to bring progress. Against her husband's wishes, she trains to become a solar technician. Four months later, the women return to the village, bringing with them much-desired know-how. They explain how the houses can be supplied with solar energy. Little by little, solar power is finding its way into people's everyday lives. Through their actions and their training, the women subtly raise questions about the meaning of modernity -- and the position of women in society.
