Live without food? Draw energy from the environment—like plants? Is this realistic? The film follows a group of people who claim that it is possible to nourish oneself with light. Marek, a Polish bioenergy therapist living in Greece, did not eat for 63 days and lost more than half his body weight, which almost cost him his life. Krzysztof has just returned to Poland after a long stay in India, where he studied yoga. So far, he has fasted for a month, but he plans to finally cleanse his body and live without traditional food. Kazimierz claims that he has already done so and has been drawing energy directly from the sun for five years. Joanna has only gone without food for two weeks so far, but she believes that switching to not eating is the path to happiness for her. The protagonists, talking about their experiences, have the courage to contradict modern science.
