At San Juan de la Vega, a modest town, the Delegate is the only legal authority and stays permanently worried about the peril the Carnival brings within. Living on the other side of the tracks is José, an enthusiast of detonating homemade bombs with his gang before and during Shrove Tuesday. Saul, a devotee who has led for decades the pilgrimage of San Juanito, the patron saint, represents the third party in discord. The five-day feast brings joy and abundance to the community, but it also carries a threat that each year gets closer to a breaking point that would have fatal consequences. Faith and danger dance closely together in this deeply Mexican ritual.
