The Assailant (known as Besouro in Brazil) is a 2009 Brazilian action-drama film directed by João Daniel Tikhomiroff.

Resistance in the region of the Recôncavo Baiano is led by the elderly Mestre Alípio, master of a martial art, capoeira, used by the slaves to fight off abuse.

However, Besouro spends all of his time playing capoeira in street circles, with the consequence that Alípio is killed by the police.

Trying to fight off the spirit, Besouro accidentally trashes a work fair, making the guards chase him.

He jumps into a river, after which he meets a spiritual teacher, Dona Zulmira, who gives him a choker granting him corpo fechado, making him invulnerable to all attacks and weapons except by the tree known as ticum.
