The documentary "@predioposto13 - Meu Nome É União" weaves together memories of the former Hotel União, located on the banks of the Presidente Dutra Highway, in Nova Iguaçu, Rio de Janeiro. Deactivated for about 20 years, it is an icon of Baixada Fluminense for being a point of reference for residents and a large mural of the carioca xarpi. The film exposes and discusses the filmmaking process itself, the value of urban art and capitalism through a collective lens.
