Watch Sadisflix. Every day, at sunrise, the Sítio Porto Alegre School students arrive by boat for another school day. As Professor Rui seeks to catch the attention of the 3rd grade children, new principal Leidi and school boatman Raimundo try to solve the lack of fuel problem caused by the little money sent by the government. These are rainy days in Curralinho township, on Marajó Island, where a school community resists.
