Cuba’s Crossroads–Hope, Rock and [R]Evolution, the sixth in a series of films on sustainability issues by Pace University students and professors, provides an intimate snapshot of life on this Caribbean island at a remarkable juncture–between dictatorship and freedom, propaganda and the World Wide Web, suspicion and hope.

Over the course of one remarkable week in early spring, the governments of Cuba and the United States cautiously let down their guard, offering a glimpse of what normal relations might look like between nations separated by less than 100 miles of sea but long divided by clashing ideologies and Cuba’s totalitarian leadership.

The film takes viewers from Cuba’s unspoiled beaches to an organic farm supplying the mint for Havana mojitos, from its historic streets and self-sufficient neighborhoods to the throngs at a Rolling Stones show. Interviews with Cuban citizens and scholars, visiting tourists, and eager American businessmen convey the array of hopes and concerns related to the expansion of trade with the United States in both goods and ideas.
