Documentary going behind the scenes of Jessica Ennis-Hill's bid to defend her heptathlon title at the Rio 2016 Olympics, seen through the eyes of her coach Toni Minichiello. Having turned a 13-year-old schoolgirl into the golden girl of London 2012, Minichiello has a unique insight into what makes Ennis-Hill tick and what it is like to coach an Olympic champion. With their greatest challenge perhaps still to come - attempting to defend the Olympic crown in Rio despite long periods away from the sport due to motherhood and injury - we hear how Minichiello and Ennis-Hill plan to rule the world once more in Brazil.
