The documentary covers the first phase of the brazilian metalworkers' strike in 1979. It was made to be shown to the workers during the truce between the two phases of the strike, with the aim of mobilizing them for the second phase. The film shows the large assemblies, with more than 100 thousand metalworkers, in the Vila Euclides field, in São Bernardo do Campo; the mobilization for a vigil at the Union; the resulting street conflicts and the triumphant return of the board, headed by Lula, in the great assembly in which the truce was proposed.
