To tie in with the 60th anniversary of the Universal Declaration of Human Rights, More4's True Stories is exploring independent minds.More4's True Stories: An Independent Mind traces the lives and tales of eight very different people.Among them are the Moustache Brothers - a comedy troupe from Burma who're under house arrest because they're banned by the Burmese military regime.As such, the three-strong act performs illegally for tourists from their home in Mandalay. There's reggae singer Tiken Jah Fakoly, who in December 2007 was declared persona non grata in Senegal after criticizing the president.What ties the above two, and other stories, together, is that in each case there's a desire to exercise a freedom of expression and the right to have an opinion.It's an insightful look into eight very different world's, but world's that still make an impact because their stories are all-powerful.
