Frank is beaten and kidnapped, while Marisa barely escapes. She receives help from the young South African Biko, who helps her to escape the men. Marisa and Biko find out that people are abducted to be cannibalized for the trade in organs. Finally, the two try to find frank and save him.

Inspired by the true story of Siseko Ntondini and Piers Cruickshanks, who together won gold in the 2014 Dusi, Beyond the River delivers a nail-biting adventure story about the triumph of the human spirit.
