Carnival enlivens all the streets of Brazil, while a secret haunts the group of young people who need to survive this night. Someone knows something they shouldn't, and it's going to turn what would be a party, in a massacre.

The plot follows the emergence of a new Ghostface during the Carnival season, as a series of murders reignites past traumas and expands the list of suspects, while scars left by the previous Carnival threaten to reopen.
