Caoimhe investigates people's experience of sex education. Where does our knowledge and understanding come from? Are we learning in school, from parents, from peers or online? Caoimhe visits universities around the country to find out how they are informing their students about sex. She talks to teachers responsible for providing sex education and youth group representatives who are asking for more to be done. She also meets with young men in the Shankill area in Belfast to discuss where and when they started learning about sex. Clíona Saidléir, of Rape Crisis Ireland, talks about pornography and how it could be normalising sexual violence, and Caoimhe chats to a young woman who shares the story of how one video taken without her consent has impacted her life.

In the final episode of the series, we focus on the environment and how some young people experience eco-anxiety that stems from climate change. We meet young activist, Anna Kernahan and friend Kay, who participate in a Fridays For Future School Strike in Belfast city centre. It's the 115th week of their strike. Caoimhe attends an Environmentalism lecture in Queen's University Belfast led by Professor John Barry who tells her about the worries and eco-anxiety his students have about the future of the planet. One student and young dad talks to Caoimhe about his concerns for his son's future if nothing is done about climate change. Martha, a vegan living in Dublin, gives Caoimhe tips on how to shop more sustainably. And Aoife de Bhál, who works in The Bog Meadows, reminds us how we can all play our part and become more connected to nature.
