For Maggie Rayburn, wife, mother and secretary at a munitions plant, life is pleasant, predictable and secure. When she finds proof of a high-level cover-up on her boss's desk, she impulsively takes it, turning her world upside down. Propelled by a desire to do good - and a new-found taste for excitement - Maggie starts to see injustice everywhere. Soon, her bottom drawer is filled with 'evidence', her town has turned against her, and she must decide how far she will go for the truth.

Meanwhile, in Iraq, Captain Penn Sinclair's hasty orders have disastrous results. In an attempt at atonement, he reunites with three survivors to expose the truth about the war. Now and Again examines the interconnectedness of lives, the limits of knowledge and the consequences of doing the right thing.
