Thunderheart

FBI agent Ray Levoi is thrust into a strange new world when he is sent to solve a murder on an Indian reservation. Hand-picked because of his part-Sioux ancestry, Levoi is teamed with a legendary older agent to capture a radical Indian protester. There, Levoi encounters the local sheriff and the tribe's religious leader, who knows secrets about Levoi's own lost heritage. As Levoi's awareness of the native culture grows, so does his belief that the U.S. government has framed an innocent man.
