In 1820s rural England, a young girl is tricked by tales of marriage from a villainous Squire. When she becomes pregnant and disappears, a gipsy lad is blamed.

In 1894, French officer Alfred Dreyfus is wrongly convicted for the treasonous acts of another man, Major Esterhazy. When investigations begin into the dubious evidence used in the trial, an institutional coverup begins, aided by fears of army disgrace and anti-Semitic paranoia against Dreyfus. But a determined group, headed by prominent author Émile Zola, leads a mounting public call to reopen the Dreyfus case.
