Two Czech electricians return to the Zambian village where, five years earlier, they installed solar panels to provide electricity to the school, clinic and several homes. To their dismay, they find their system in complete disarray. Despite their altruistic intentions, they didn’t take into account the Zambians’ differing ideas of problems and solutions, humanitarianism and gratitude. Mareček’s camera acts as observer following the two men as they try to repair the system and understand the needs of the people they are trying to help. Cultural differences set off many humorous moments.
