On May 25th 2000, in Genova, a big demonstration is opposed to Tebio, the first international exposition-market about biotecnologies. The image of scientific meeting and of false neutrality (which it wants to inform correctly about the biotecnologic searches) is just an appearance of a different objective: to offer a window to the biotech multinationals, born from the fusion of chemical-pharmaceutics giants, that have in their hands of this kind of market called "science of life". Against all this arises Mobiltebio, the big coordiantion of associations against genetic manipulations. This documentary tells about the demonstration day.
