Filmmaker-griot coming from the theater, it was with a camera, while the war in Vietnam occupied everyone's minds, that Sarah Maldoror gave visibility to the African wars of decolonization: Angola, Guinea Bissau, French Guinea, Cape Verde... Her short film Monangambée addresses the torture by the Portuguese army of a sympathizer of the Angolan resistance. At the end of editing, Sarah Maldoror approached the members of the Art Ensemble of Chicago during a Parisian concert and offered to add sound to her film. The next day they watched the film, were convinced and recorded their first soundtrack for free as evidence of African-American solidarity. Shot in Algiers, Monangambée is a film about torture and, more broadly, about the incomprehension between the colonized and the colonizers. It is based on a novel by the Angolan writer Luandino Vieira, then imprisoned by the Portuguese colonial power.

Domingos is a member of an African liberation movement, arrested by the Portuguese secret police, after bloody events in Angola. His wife goes from a prison station to another, trying in vain to find out where he is.
