In the depths of the Brazilian Amazon, isolated communities live hundreds of miles from their local state capital. Without any means to protect themselves against powerful landlords, or abusive husbands many turn to the courts for help. With little access to state services, one judge has gotten creative and taken justice down the river to reach those in peril. Filmed in an area of Brazil seldom seen on screen, the documentary follows the judge and his courthouse boat as it meanders down the Amazon River reaching the far-flung indigenous communities.
