How can this be? Nathan and Naomi had a life made in heaven for forty years. Their lives together are explored in an eventful search for identity through family and historic incidents from their Aboriginal and Japanese-Canadian backgrounds. Both enjoy great success in their quests. Then tragedy strikes and dementia steals their lives. JIGSAW tells their story from both perspectives - that of the sufferer and of the caregiver. In the end, love is tested and triumphs over the despair and challenges.
