Set 100 years ago along the US/Mexico border, “The Tears of La Llorona” retells the Mexican myth of the Weeping Woman. Llorona has become infamous for stealing children in the night, but the Calaveras — a band of mariachi women — guide us through a reimagining of her origin story. Resurrected from the dead, she seeks vengeance on her murderer. But fate creates uncertainty within Llorona after chance encounters with her husband, a girl she finds kinship with, her lover, a white boy exploring Mexico for the first time, and an old Abuelo who is her connection between the living and spirit worlds.
