In an oppressive one party state, a mechanic with hiccups makes a mistake fixing a government vehicle which means the secret police fail to carry out a raid on dissidents. The mechanic becomes an accidental hero and the resistance movement adopts a new strategy of annoying tiny mistakes, using the secret sign of hiccupping as a password. The movement spreads and the country starts to become ungovernable. The secret police finally catch up with the mechanic and imprison him. This causes a general uprising and the government is toppled. The mechanic, who has not realised what is going on, finds himself made the new president. He still has hiccups.
A movie, I think
