Willy Wonka is the owner of a chocolate factory. Since his ingenious patents for chocolate making are the envy of his competitors for years Willy has been forbidding anyone to enter the factory. One day an international contest is announced: the five people who find a golden coupon inside a “Wonka” chocolate bar will be given a tour of the factory and for their whole lives get its products free. Five lucky children, accompanied by their parents, can visit the mysterious factory. Only one, however, Charlie, the poorest and most honest, will manage to pass the various tests that Willy Wonka will set him.
