Fast food is full of fat, sugar and preservatives. It’s slowly killing us, contributing to a worldwide epidemic of obesity, diabetes and heart disease. This documentary targets one of the world’s most famous but equally controversial companies, McDonald’s. Six members of the public are given an all-access pass to McDonald’s and set out to ask the tough questions about what goes into the food they eat. As we follow this intriguing journey it will be more than a program about fast food. It’s a social experiment. One that tests whether people, faced with overwhelming evidence challenging their long-held prejudices, can ever accept the truth.
