Granny Power is an unusual documentary on an organization of aged fighters and the age old problem of fighting poverty, hunger, inequality and systemic injustice perpetuated by capitalistic politics of war and trade. It is commonly believed that young people are militant as long as they are young and lose the spirit of protest and as they grow old and become 'wise'. But as the members of the 'raging grannies.' exemplify by their act and attitude that is equally possible to become more militant and radical precisely because of growing old backed by wisdom and experience.
