The killer in me.

Four celebrities take a pioneering genetic test to expost any known genetic risks from 11 disease areas in their cells. Broadcaster Fiona Phillips' mother had both breast cancer and Alzheimers, ex-footballer John Barnes has a very bad diet and a history of heart disease in his family, DJ Toby Anstice was adopted so he has no idea of his genetic inheritance and presenter Andrew Neill who drinks and smokes heavily and has a busy stressful life. But when the results are back, do the celebrities really want to know what kind of risk they're under? As they await the test results they all discuss what it would mean to them to know what they might die from in the future and we see them as they are confronted with the results.
