Abissal (2016)

By starting a project of researching the life of a grandfather who he have never met, the filmmaker from Ceará, Arthur Leite, began to investigate the history of his own family. The deeper it gets, the more it departs from the original idea, and he realizes that the character is actually his grandmother Rosa – who, facing the camera, starts to make unexpected revelations about this unknown past.

Unfortunately the movie Abissal is not yet available on HBO Max.
