"The Voice of Innocence" is a documentary that shows how, starting in 1959, the Cuban Revolution put into practice a comprehensive and universal policy of safeguarding the rights of the child, even under the multiple difficulties resulting from the economic, commercial and financial blockade imposed by the United States more than six decades ago. Cuba is one of the main signatories of the Convention on the Rights of the Child, signed on 20 November 1989, when the country had already made extraordinary progress in protecting the rights of the child, in comparison to developed countries, such as the United States, which as of today hasn't yet ratified the Convention.
