Brandi, a free-spirited woman, stumbles home on a Sunday morning, slightly drunk, and finds herself attending service at a Spanish-speaking, Pentecostal church. She befriends Catrina, a teenage girl going through a cultural crisis of faith. Brandi becomes the devil on her shoulder, persuading her to follow her rebellious impulses. Catrina is torn between her ties to her community and the desire to join the outside, secular, Americanized world.
