Chicago Reader review:
Peter Fonda's first venture as a filmmaker (1971) is close in spirit to his father's pastoral dramas. Seven years after he abandoned his wife and son to become an outlaw with Warren Oates, Fonda returns home and takes a menial job on what was once his own ranch. The back-to-the-land sentiments often have a dilettantish, posthippie feel, but Verna Bloom has great authority as the wife and Fonda's direction is appealingly modest and lanky.
Here (and above) is the trailer.
