Uptight New York City executive, Michael Cromwell, pursues his soon-to-be ex-wife to South America and returns home with the son he never knew he had—a boy raised in a tribal village in Brazil. Armed with only his blowgun, the 13-year-old Mimi-Siku discovers that the world outside his jungle home is indeed a strange place. A man learns he has a thirteen-year-old son who was raised in the jungle and brings the boy to New York City, turning his life upside down in the process.
