Rio de Janeiro. A family hotel whose clients reflect Brazilian society, multi-racial, with starkly contrasting backgrounds, and destitute. Rio is the perfect backdrop with its dictatorships, drug wars, child gangs and violent policing tactics. The first victim is found decapitated in bed, the head lying on the floor of his room. An eerie Mona Lisa smile on the victims face and no evidence of a struggle indicate a murderer received as a friend. Other hotel guests are eventually killed, all decapitated.
