In December 1967, a Cuban film crew led by Santiago Alvarez, the veteran polemicist, travelled to Hanoi. They shot the footage which constitutes this short documentary all in one day - Tuesday 13. The film is the story of that day and what happened to the North Vietnamese people in the course of it.
