Paul Bonnard arrives in Timbuktu in search of a guide to escort him into the Sahara desert. American Joe January takes the job despite misgivings about Bonnard's plans. Dita, a prostitute who has been deeply moved by what appears to be Bonnard's spiritual nature, follows the two men into the desert. Eventually the trio arrives in the ruins of a lost city, where Bonnard hopes to find the treasure his father sought years earlier before disappearing. But what Bonnard finds alters him in unexpected ways, with tragic results.

SOLDIER BLUE (Ralph Nelson, 1970)
After a cavalry group is massacred by the Cheyenne, only two survivors remain: Honus, a naive private devoted to his duty, and Cresta, a young woman who had lived with the Cheyenne two years and whose sympathies lie more with them than with the US government. Together, they must try to reach the cavalry's main base camp. As they travel onward, Honus is torn between his growing affection for Cresta, and his disgust for her anti-American beliefs. They reach the cavalry campsite on the eve of an attack on a Cheyenne village, where Honus will learn which side has really been telling him the truth.

BARQUERO (Gordon Douglas, 1970)
Jake Remy leads a gang of outlaw cutthroats making their escape toward Mexico from a successful robbery. Barring their way is a river--crossable only by means of a ferry barge. The barge operator, Travis, refuses to be bullied into providing transport for the gang and escapes across river with most of the local populace--leaving Remy and his gang behind, desperately seeking a way across. A river-wide stand-off begins between the gang and the townspeople, both groups of which have left people on the wrong side of the river.
