Stephen and Mark track down the Northern Rhino only to find that it is declared extinct in the wild while they are held up at the border by a refugee crisis. The only viable breeding Northern Rhinos in the world are in a zoo in the Czech Republic. There are five of them left on the planet. But they have never bred successfully. The zoo has agreed that all five animals should be immediately returned to Kenya in the hope that returning home will induce them to breed. If it doesn't, then they will be fertilized artificially. The hope is that these five will save their entire species from extinction. Transporting a rhino is dangerous and complicated – moving five is tougher. They'll have to undergo intensive crate training and then a blast of plane training before they can even be moved. Fry and Cawardine will be there as these majestic beasts undergo this rigorous and time-consuming process - the process that may help to save them. They'll join them on the flight – a special charter – paid for by a number of charities including Back to Africa – and they'll be there to witness the incredible security and care that they receive once they land. Will they settle down, will they survive ‘quarantine', and what impact will ‘wildness' and Africa have on them?
