Belinda (Nicole Puzzi) and a group of young university friends arrive at a coastal campsite near a beach for a leisure vacation. Nearby, Adilson (Waldir Siebert), a local young man infatuated with Belinda, stays in another tent with his family and attempts to get close to the group under the guise of offering help. During an evening walk, Belinda and her friends stumble upon a secretive Afro-Brazilian Candomblé religious ceremony on the beach. Their intrusion into the ritual triggers an escalating sequence of sexual indulgence, criminal incidents, psychological breakdown, and sinister atmospheric occurrences that disrupt the peaceful seaside trip and entangle the group in danger.
