After the war the zany Williard brothers and their paramours go looking for adventure and find all they can handle when they decide to see if there really is a dinosur still living deep in the Congo. Flying a beatup old seaplane, the brothers are shot up, shot down, chased by the Mafia for carrying drug money they don't know they have, captured by pygmies and forced to undergo the dread palm wine drinking contest, where failure means being fed to Mokele Mbembe--and if they survive all this, the Godfather is waiting back in New York to feed them to his pet shark.
