The idea of gender is becoming more talked about. But what is it, and why does it matter? Cara explores drag with a trans man in LA, discovers a third gender culture in Mexico and experiences a ‘gender swap' in Spain. Along the way, she confronts her own gender fluidity and masculinity.

Love has always fascinated Cara. It's time to think beyond monogamy. Cara takes a DNA test in London and has a brain scan in the USA to reveal the secret science of love. She also explores solo weddings in Japan, polyamory in South Africa and non-monogamy in LA.

Cara consults a cosmetic surgeon and investigates where our ideas about beauty come from. She explores colourism in South Africa, plastic surgery in Colombia and talks body positivity everywhere.
