An explosion of gender identities and sexual orientations is currently underway: They are becoming more flexible, more diverse and, above all, more visible. One is non-binary, gender fluid, genderqueer, trans or cross gender, bisexual or pansexual. There is also strong opposition to this. The Catholic Church sees the "gender ideology" as a "postmodern aberration", and all over Europe thousands of people take to the streets to fight the supposed "gender madness" and to promote the heterosexual nuclear family as the basis of a healthy society. What is it up to the strict distinction between man and woman? Do we no longer need our classic gender roles? Is this so-called binary concept still tenable? This documentary examines these questions from a scientific perspective and shows that the world is definitely more colorful than we long believed.
