An investigation into a worldwide ecological disaster that could endanger the whole of humanity. The future of our food resources depends on one small insect - the western honey bee, or Apis mellifera. Indeed, it is the most important agricultural pollinator on our planet given that one third of our food supply depends directly on pollination from bees. This documentary tells the story of a worldwide ecological disaster that has been waiting to happen for several generations. It was filmed over an 18-month period in France, Germany, the U.S., Canada and Scotland and retraces the various leads carried out by research scientists in order to try and understand and to stop the declining numbers of domestic and wild bees. Scientists are not the only professionals to figure at the centre of this drama. Beekeepers are in the front line, and striking contrasts exist among beekeepers' experiences in different countries, in various economic situations. The documentary seeks to understand how the long-enjoyed harmonious relationship between man and bee has now undergone such a radical change. It seeks to find a solution that goes beyond science. A solution that cannot be found without thoroughly re-examining our agricultural practice and our model of society. Can we rise to the challenge?
