In the winter of 1992, a New York scientist isolated the material that love is made of: it is an unbelievable hormonal matter composed of three chemical elements. Ten years after that discovery, director Ari Folman goes out on a two-year journey in an attempt to investigate the material love is made of, as it expresses itself in eight unique and charming love stories. Alongside these love stories, the film hosts scientists, biochemists, geneticists, psychologists and philosophers, all of them are real, but in Rotoscope animation, brimming with fantasy, color and imagination.
