O Mensageiro das Trevas (2000)

Overview

A group of scouts set out to camp in a cursed forest, where an ancient legend tells of Boni Coveiro, an evil spirit that haunts the place. One of the team members, obsessed with solving the story told by his grandparents, performs a satanic ritual with the aim of summoning and controlling the supposed cursed entity. However, little did he know that the legend was true, and that his disbelief would lead him to awaken the fury of a demonic being thirsty for revenge. From that moment on, terrible deaths begin to occur among the team members, with nothing they can do to stop the massacre.
