Despite living in a postapocalyptic world and despite the fact that Sarah seems unconcerned with their racial difference, Ralph cannot overcome the inhibitions instilled in him in a racist American society.Ralph regularly broadcasts on the radio, hoping to contact other people. Eventually, he receives a signal from Europe, indicating there are at least a few other survivors. Things become vastly more complicated when an ill, white Benson Thacker Mel Ferrer arrives by boat. Ralph and Sarah nurse him back to health, but once he recovers, Ben sets his sights on Sarah and sees Ralph as a rival. Ralph is torn by conflicting emotions. He avoids Sarah as much as possible, to give Ben every opportunity to win her affections, but cannot quite bring himself to leave the city. ........
