Raid into Tibet is the only available film of the Tibetan guerilla fighters who carried on their resistance efforts in Tibet from the remote Mustang area of Nepal from 1960 to 1964. In May 1964, British journalist George Patterson - who had lived in Eastern Tibet before the Chinese invasion - bluffed his way into the remote Dzum valley in northern Nepal where a small detachment of the guerrilla force was based. Patterson was accompanied by a film crew － director Adrian Cowell and cameraman Chris Menges. They met with the leader, a man named Tendar, and tried to convince him to allow them to film a raid inside Tibet. Getting permission from their headquarters in Mustang would take several days.
