Divorced Ethnologist John Parker loves his two boys, Al and Terry, and misses them terribly when they have to leave his archaeological dig at the end of the summer. While Al goes to military school, Terry returns home and learns that his mother, Grace, has married Dr. Phil Shumaker, a stable man who can provide the home that Grace never had with John. When John gets a note from Terry saying that Grace has married and he wishes he were dead, John decides to give up his work and go to his sons. He visits Al at military school first and asks his assistance in helping Terry to accept Phil as his new father. Though the terms of the divorce prevent John from seeing Terry at home, he takes a place near them and asks Al to keep in touch with him about Terry’s progress. Though Phil tries to be a good father, he does not understand Terry and makes rules that are impossible for the child to follow.
