It's the sort of twist no screenwriter would dare invent: "Free Leonard Peltier," a persuasively well-researched and often infuriating documentary about the American Indian Movement activist convicted nearly a half-century ago of killing two FBI agents,

Jesse Short Bull and David France's documentary tells Peltier's story all the way through President Joe Biden's commutation.

The commutation will allow Peltier, who has long maintained his innocence in the killing of two FBI agents, to spend his remaining days in home confinement.

Sundance: Jesse Short Bull and David France's documentary about the American Indian Movement member who was imprisoned since 1976 for killing two FBI agents is a disappointment.
