Sadie Proffitt and her husband David, 50, are a retired couple who move from Florida to Texas to be closer to Sadie's son. While Sadie is friendly with many residents at the sprawling apartment complex where they live, David is partially paralyzed and often stays inside. On Oct. 9, 2000, in the middle of the night, tragedy strikes when a rapidly moving fire erupts at the apartment complex, and several people are killed in the inferno. When investigators begin researching the source of the blaze--some aspects of the disastrous incident just don't add up. It will take experts many months to sort through the evidence and find the truth behind the fire--and finally charge an unlikely suspect with murder.
