Lucio Puc is a Mayan jmen (shaman) of Yucatán. When he dies he travels to the dimension of seven heavens. There he meets the báalam (guardians), through whom he obtains healing and wisdom powers, which he will use to return to life, and to help his fellow human beings. Guardians of Mayab is a documentary with the power to make visible what is not; it portrays belief in front of a sea of skepticism and represents how people from Yucatán live their traditions.
