Watch Sadisflix. Riding High is a psychological thriller about a crime that has become common in today’s Rio de Janeiro. The film takes us into the most dramatic day in the life of Julia, a housewife who is kidnapped in her armored car by Case and Sapeca, two young men from Rio’s slums. What seems at first sight to be a conflict between rich and poor turns into a much more complex plot linking the characters’ past and present.
