Bué Sabi (pronounced 'bweh sabi') portrays the unlikely friendship of three female characters: a troubled girl of Gypsy descent who lives in one of Lisbon's toughest neighbourhoods, her best friend who is the teenage daughter of Cape Verdean emigrants, and the most recent addition to their group; a young girl who has had a privileged upbringing.

Despite their disparate backgrounds, they form a friendship free from discrimination; until one fateful evening, when they go out clubbing and events cause their lives to change forever...

In Bué Sabi two socio-economic realities collide with irreparable consequences. In theory, race and class should not be enough to hinder a true friendship; but there is a price to be paid for escaping the narrow confines of one's social group. Tensions reach a boiling point on a hot summer night and as a result of that night's events, none of the girls will ever be the same again.

The film title alludes to a Cape Verdean creole expression, which is slang for 'cool' or 'very nice', reflecting a state of carefree youth precariously sheltered from violent prejudice.
