Katie Smith presents a show all about survival and Dutch triathlete Els Visser knows exactly what it takes to survive against the odds. In 2014, Visser was a medical student travelling in Indonesia when the boat she was on started to sink. She made the decision to swim eight hours to a deserted island where she was finally rescued by a passing boat the next day. This not only saved her life, but it also set her on a career path that she never once imagined would be possible. She shares her story and how surviving a shipwreck led to her becoming a successful triathlete.

Danny Rensch has helped change the way chess is played, but his own path to chess mastery is one of trauma, isolation and resilience to the point he says chess saved him. He shares how chess was his tormentor but also his mentor with this talent for the game taken advantage of when he was younger and growing up in what he describes as a cult. He now says chess has helped provide solace through how he’s now helping others enjoy the game.

Eric Murangwa Eugene explains how football saved his life during the Rwandan genocide. At the time, he was an 18-year-old goalkeeper for one of Rwanda’s top football clubs. He tells Jake Warren why his life was saved when gunmen recognised him as a footballer.

Not by the Playbook also catches up with Kate Hwang – a former Kansas City police officer injured in the line of duty – after her medal success at the World Para Athletics Championships.
