SWEETWATER is the little-known story of basketball player Nat “Sweetwater” Clifton who became the first black player in the NBA. The movie starts with Jim Caviezel in a cameo as a sportswriter who gets in a cab and recognizes the older Sweetwater as his driver. He asks incredulously why Nat is driving a cab. Jump back to 1949, where Nat’s playing for the Harlem Globetrotters in an exhibition game with NBA world champion Minneapolis Lakers. The rest of the movie shows how Nat broke the racial barrier to become the first black player with the New York Knicks.
