"Map of Destiny" is the true story of an ordinary Long Island housewife, Lorraine Pace, who got breast cancer and then learned that 20 of her neighbours also suffered from the disease. But when she realised that the medical and science 'establishments' didn't believe in 'clusters', she got mad and set about to prove them wrong. With no background in science or political advocacy, she single-handedly mobilised her oncologist and local health department to design a study; her community newspaper to publish the study's results; the neighbours to collate the data; a university epidemiologist to analyse the data; and both regional and national politicians to back her efforts.
