Priscila, sister of MMA fighter Vitor Belfort, disappears in Rio de Janeiro. After a few days, in despair, Vitor enters the octagon for a world title fight wearing a t-shirt saying "COME BACK PRISCILA". The police struggles to find a lead.
With an arrest, the hope for a solution of the case rises. The involvement of drug dealers generates police operations in the slums, where Priscila may be on her own free will. Her past is ignored by the police and distorted by the media.
The lack of answers about the case casts doubt on the work of the police. Family and friends try to map Priscila's past to understand her change from radiant to introvert, which ends up in a suspicion more intimate that they would like.
The wounds of the case remain open. A lot of pain, a computer without files and strange behaviors keep and enormous "if" alive. The Belfort family turns grief into fight.
