June 27, 1980: a DC–9 flying over the Tyrrhenian Sea breaks up mid-air and crashes near the Italian island of Ustica, killing all 81 people on board. The official version blames the "structural failure" of the plane, but a young journalist smells a cover-up and starts fighting to break free the truth from the 'invisible wall' of lies built by politicians and air force higher-ups.
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.
