Blue. The invisible workers of the night

The film takes us on a nocturnal and subterranean journey inside the TBM, the tunnel boring machine used to dig tunnels and subways all over the world. 

The departure of the TBM from one station and its arrival at the next mark the stages of our film, a passage that goes from the dark of the work underground to the breaking down of the bulkhead that frees the workers from the bowels of the earth and from their endless night. 

The film turns its gaze on inaccessible and invisible places and reveals the inseparable link between men and machines, between technology and manual labor, between safety and ancestral fears, between planning and chance. BLU is a tribute to all invisible workers.
