Former drug addict Noah Galloway's worst fears are realized when he is arrested for an arson fire in which twenty-six people were killed six years earlier, and he persuades reclusive defense lawyer Andy Carpenter to take his case, based on their shared loved for Carpenter's dog Tara, and though Noah confesses to the crime, he also swears he does not remember anything about the night of the fire, and Carpenter stalls for time while giving his team a chance to mount an investigation that grows deadlier every day.
