Michele Apicella, Goffredo, Mirko, and Vito are four high school friends who were on the forefront of the political protests that characterized the second half of the 1960s. Now a few years older, the four friends are no longer politically active and struggle to come to terms with their present. Intellectually marginalized and disenchanted with contemporary society, they form a collective consciousness group to try to understand what to do with themselves.
