Mr. Arvidsson has died in the interim; Gunnar and Ulla now share the house with a large Greek family. Gunnar welcomes him and consoles him as best he can, but the house is so crowded, he has Ingemar live with Mrs. Arvidsson in another house. Meanwhile, Ingemar becomes the object of contention between Saga and another girl. When they start fighting over him, he grabs onto Saga's leg and starts barking like a dog. She becomes upset by his strange behavior and gets him into the boxing ring. During the bout, out of spite, she tells him that his beloved dog (which he had thought was in a kennel) was actually euthanized. This, along with his mother's death, is too much for him and he locks himself inside Gunnar's one-room "summer house" in the backyard. While secluded here, Ingemar reflects on the death of his mother, the loss of his dog and a changing world. Ingemar uses the experiences of others and of his own personal loss to reconcile a life which is sometimes tough.
