Based on the eponymous bestseller by Allan and Barbara Pease: Jan and Katrin are nothing less than a dream couple. Both are immensely attractive and hugely successful in their respective jobs, yet ever so often, some distinct distinctions between the two come to surface: However smart Jan might be in his professional life, he still falls for the most blatant sexual signals. On the other hand, Katrin defies her own intelligence when she suddenly seems to be flattered by the advances of macho Jonathan. All this leads to the dramatic question: Have evolution and emancipation really failed us in our attempt to become more enlightened human beings?
