After a sudden murder of her brother and father, Renata, a high-ranking cop, infiltrates the District 8 crime syndicate. She competes in MMA fights to lure the mastermind, uncovering their crimes and fighting for her life.

After the murder of her younger brother, Alex, and the kidnapping of her father, Tomi, by a criminal syndicate known as District 8, Renata seeks answers and retribution. James, the owner of an MMA business on the 3rd floor of the District 8 building, advises Renata that to meet the main leader of District 8, she must become a prominent and useful figure to them. Renata then trains hard in martial arts with Ferri, who guides her until she becomes a police officer 10 years later. In one of the undercover operations led by Renata, she finds Tomi, her father, murdered in one of District 8's gambling dens. Ten years ago, Tomi was kidnapped by Sandra, one of the leaders in District 8 who controlled the prostitution business. Tomi had to become part of Sandra's "collection" to prevent District 8 from attacking Renata as well. Renata continuously tries to find ways to destroy District 8. Behind her position as a police officer, she also fights her way up the ranks in the MMA arena to be noticed by the Leader.
