This is a film comprised primarily from footage shot by the exploring team of Mr. and Mrs. William Phillips, nee Bill and Eve Phillips, a minor league version of the better-known Martin and Osa Johnson. It, between tons of shots of bare-breasted Choco and Cuna Indian women, has a flimsy plot about a party of engineers "seeking" a continental highway route from South America through Central America to the United States.
