A group of men in Senegal volunteer as human bait to catch flies carrying a parasite that once blinded hundreds of thousands of people throughout Africa. Following the lead of Africa’s leading medical entomologist, Daniel Boakye, the group of men work towards freeing the Gambia River from the vicious disease. Legendary Senegalese singer Baaba Maal provides the soundtrack for this lyrical celebration of the work that has brought his country within sight of a once unthinkable goal: eliminating river blindness.
