José Pedro de Freitas, better known as Zé Arigó, was a simple man who lived with his wife Arlete in Congonhas, Minas Gerais. During the 1950s, a time when Spiritism was not as well known and respected in the country, Arigó became a symbol of hope through his surgeries and spiritual cures. Based on a true story, Arigó, with the help of the spirit of Dr. Fritz, performed numerous spiritual surgeries on people from Brazil and the world.
Split into three chapters, "Cabrito" tells the story of a man haunted by his loved ones. The film begins with the story of his father and how the family became cannibal. The second part focuses on his mother and how she awakens the worst in her son with her twisted religiousness. The last part is focused on the main character's final catharsis, when he kidnaps his first love, Rosalita, and reproduces the inhuman bizarre caring to which he was subjected in his family relations.
