Ethan was a ten-time MMA champion—until prison took it all. Now he works as a cleaner at a boxing club, hiding his past. Then a challenger storms in, and his cover blows. He beats her, saves the club, and starts digging. A viper tattoo on an underground fighter points him toward his father‘s killer. He enters the underground ring, follows the trail, and finds a web of gang bosses and dirty capital. In the CFC national tournament, he defeats the brutal club fighters, survives poison, frame-ups, and ambushes—then exposes the match-fixing and IPO scams to the world. The viper falls. So do the men behind him.
