The San Antonio prison, in Cochabamba, is the smallest prison in Bolivia. It is not difficult to deduce from this data that overpopulation and overcrowding, so common in Latin American prisons, reach atrocious levels there. But it is one thing to deduce it and another to observe it from the inside, as Olmos’s documentary does, which reveals an incredible miniature jail/city where prisoners can live with their families (or spend the night with prostitutes) and set up their own businesses (legal or not), without the State or society seeming to care too much. Three stories, told in parallel, structure the film. One is that of Ramón, a prisoner for drug trafficking who dresses up as a clown for the children in jail. Another is that of Sergio, a gang member accused of double homicide who awaits his trial while he makes tattoos, sells drugs and records a hip hop album. And the last one is that of Guery, a thief who only wants to leave San Antonio to steal again. Life stories like so many others, which reveal many of the complexities, contradictions and debts of Latin American societies.
