A volunteer helps a mentally retarded girl. Close-up of a sign 'State Department of Health, Mansfield. State Training School and Hospital'. Exterior of the building. A man opens a locked door with a key and enters. Superintendent Verne Kelly, mentions help from the University of Connecticut and its students, participating in a cooperative education program, called the "Big Brother and Big Sister" program, particularly for Mansfield children who have no parents or visitors. He quotes one child as saying "a big sister is someone who knows all about us and still likes us."A retarded girl helped by a volunteer tries to bowl. At first she cries. Then she succeeds and is happy. A boy stands nearby. A wheelchair in the background. The woman and the girl smile.
