A group of workers from the port of Genoa, organized under the autonomous acronym C.A.L.P. (Collettivo Autonomo Lavoratori Portuali). They gather in an assembly to discuss the difficulties in dealing with the union, to denounce the passage of ships transporting weapons and explosives destined for war zones, and to reflect on the need to build networks and incorporate an intersectional approach into their political actions. Portuali is a film that tells the story of work and the union world from the inside, as well as the various forms of activism, laying the groundwork for a new narrative of class struggle.
