Marcela Acuña is the number one female boxer in the country, with more than 30 wins and a few losses, but that's all in the past. Director Matilde Michanie uses the life of this boxer as a starting point, a long flashback that begins when "La Tigresa" heads to Luna Park, the cradle of Argentine boxing, to fight for the world title. In this way, she introduces us not only to a personal life story but also to the stories of different female boxers from around the world, providing an overview of how women's boxing is viewed beyond the Río de la Plata.
