But not everyone has been doing well. Thieves break into the Brannings house, and when Jeff follows them, he finds only a few lonely children in horrible living conditions, stealing to feed themselves. At Kay's insistence, the Branning family takes the children into their home. But now their daily needs are even greater, and the children have a load of griefs themselves.
