Set in the heights of the Bolivian Andes, Mamachas del Ring is the story of Carmen Rosa the Champion, a cholita and wrestler who struggles to make it on her own in the male-dominated world of Bolivian professional wrestling. In 2004, Carmen Rosa was at the forefront of a Cholita wrestler revolution. Never before had Bolivia seen an indigenous woman take her petticoats and bowler hat into the ring, and the crowds couldn't get enough. Along with three other Cholitas, Carmen became an international star, and all four were anointed the Mamachas of the Ring. The film begins in 2006, shortly after their return from a star-making turn on Peruvian TV-but their rapid success has come at a price. Jealousy and envy begin to ripple throughout the wrestling community, and eventually they are black-listed from performing in Bolivia's main wrestling league by its notoriously egotistical league commissioner, Don Juan Mamani. Betrayed but not discouraged, the Mamachas take matters into their own hands...
