After an ordinary day of classes, a hesitant student is convinced to go to the DCE, a party that takes place every Thursday on the Praia Vermelha campus of the Federal University of Rio de Janeiro. As she crosses the gardens of the School of Communication's Palace, she feels something watching her from the empty amphitheater. At the DCE, the night unfolds, alcohol flows, and the place fills with people. But the disturbing presence following her remains, drawing ever closer. Amid shadows and whispers, she comes face to face with the unknown — or something far more sinister lurking nearby.
