This film shows the effect upon infants of prolonged absence of the mother. A number of babies in a foundling home are shown. The film indicates that among infants under a year old, if the mother returns after an interval of fewer than three months, their recovery is rapid. If the absence is prolonged beyond this period, it becomes impossible to achieve contact with them, and they become passive and apathetic and begin to suffer damage to their personalities. The film suggests that it is the emotional climate provided by the mother that allows the child's mind to develop normally.
