The beautiful Teresa travels back to her remote Brazilian village of birth Bacurau when her grandmother passed away. Bacurau suffers the progress of the city of São Paulo. A dam was built which cut off all water supply for the village. The inhabitants have to get it elsewhere with tanker trucks, while the dam is heavily guarded.
The death of the grandmother brings a nice peek into the Brazilian rural funerary customs. In general, you can see a closely lit, countryside community.
There are a few weird things though and the film slowly crawls towards being a thriller. That part of the story is a bit far-fetched.
Especially the parts of the Brazilian country life are nice to watch. There is some humour, serious tones and in some ways explain how the inhabitants react to the incoming threat.
