This short film -one of the last made by the Afro-Cuban filmmaker before his definitive expulsion from ICAIC in 1972- alternates shots of the assembly of a vehicle designed for workers' transportation with the exploration of the conditions of workers' representation and political participation in an assembly held in the workshop. The radical disjunction between image and sound interrupts the logic (and etymology) in which the agglutinating force of the "assembly" and the operation of the "assembly" of the parts converge in the dissonant structure of this documentary.
