The Shout (1968)

Banned until very recently, Arteche’s clandestine documentary chronicles a group of students’ movements in Mexico in 1968.
On July 22, 1968, two rival groups of male adolescent students fought each other in the Ciudadela neighbourhood of Mexico City; the next day the city government responded by sending policemen to stop the accompanying vandalism and to arrest the perpetrators. These riot police (granaderos) attacked the students so ferociously that protests were lodged. No one could have foreseen that both of these testosterone-driven events were the opening scene of the drama of the 1968 University-State conflict which climaxed in the Tlatelolco massacre.
