Joy is living in an orphanage, since she has no family after her parents
passed away. Joy spends most of her days alone, since she doesn't
believe she will ever belong to a family again. The Roberts are a newly
married couple looking to adopt a young girl and are introduced to Joy.
Joy is very apprehensive, but agrees to go with them on a trip to the zoo.
On this trip Joy meets some unexpected friends that show her the real
meaning of family.
