Aggressive inline skating took the world by storm in the 1990s, giving birth to a whole culture and movement in the process. Since then, the sport has never stopped evolving, with skaters constantly pushing themselves to get more technical, outrageous and daring with their tricks. We introduce a Japanese skater who has won multiple world titles and is arguably the top female skater of her generation. We follow her through some dramatic ups and downs, as she embarks on the journey to defend her position as world number one.
