Lara Bloom has Ehlers-Danlos syndrome, a genetic disorder in which the structure of connective tissue is abnormal due to a gene mutation. This results in abnormally fragile and hyper-extensible tissues throughout the body which can lead to a range of multi-systemic symptoms; the effect on the body is widespread and not limited to one body system. Although widely unknown, EDS affects so many families and individuals around the world. At the age of 31, despite having barely walked more than three miles at a time before in her life due to her condition, Lara decided to try and become the first person with EDS to walk the London Marathon. The documentary follows Lara Bloom's journey as she became the first person with EDS to walk the London Marathon and features interviews with medical professionals, families with EDS and individuals who have suffered from misdiagnosis. Recognition and awareness of EDS is essential.
