Mysterious financial losses lead the Post Office to fire and prosecute village Subpostmasters, who have no way to prove their innocence.

Toby Jones, (Empire of Light, Tinker Tailor Soldier Spy, Sherlock), stars in this real-life David and Goliath story that chronicles the jaw-dropping plight of hundreds of postal workers accused of a crime they didn’t commit—but went to jail for and worse. It’s a story that UK journalists have reported on for years but once dramatized for TV, set off a firestorm of public outrage that forced the Prime Minister to act.
