Entrei em Pânico ao Saber o que Vocês Fizeram na Sexta-feira 13 do Verão Passado (2001)

The title says it all

Goti and his friends Marcelo, Eliseu, Tomás, Ido and Geison will graduate on a Friday the 13th. To celebrate, they decide to make a party in Goti's house with booze, drugs and some girls. What they didn't expect is the visit of a masked killer - dressed as Ghostface in "Scream" -, who broke into the party to murder one by one.
