1998. Havana Bay, Cuba. Isolated from the world market, with severe technological lags. These are welders and sailors who work at ASTICAR, (Caribbean shipyards), a company where they carry out everything from minor repairs to complex treatments on deep-draft ships. The process used for this is called "dry dock" and consists of a huge, floating metallic structure that is moved to the open sea, submerged for the ship to enter, then it is lifted from sea level and brought to shore to be repaired. The harsh reality of daily labor, dark and hopeless, in contrast to modern industry with robotics in action and the worker turned into another spectator of the wonders of technology. It is enough to observe the fatigued faces of these workers, who go from repairing a ship that is a symbol of movement (o progress) and a subtle announcement of the restless migratory concern among Cubans, to representing an overwhelming and hallucinating theater of masks.
