Kimberly Benson is Viper, one of Scotland's top female wrestlers. We're with Kim in Glasgow and in Japan as she fights in some of the most important matches of her career.

As women's wrestling steps into the mainstream, it's a pivotal moment in Kim's career. We follow Kim into this intriguing and sometimes dangerous world at home and abroad as she takes us behind the scenes of a rarely seen and often misunderstood yet utterly fascinating world.

We are with Kim as she competes in a series of high-pressure matches that could have a huge impact on her future career. We are ringside as she fights men twice her size in a rare match that puts male and female wrestlers in one ring to fight it out. We see her battle for a Scottish championship, and ultimately she puts everything on the line for a chance at her first ever world champion title. We travel with her to Japan to see her take part in this epic match. Can Kim survive the hectic pace of training, travelling and fighting? Can she do all this while balancing working for a living and some form of family life? On top of all that, there is the ever-present threat of injury.

While the outcomes of wrestling bouts are scripted, there is nothing fake about the physical danger these women constantly put themselves in. How far can Kim's talent, personality, skill and bravery take her in the world of pro wrestling, and what does it cost her?
