Logline: Gang affiliations are forever, refuse to do business, and death follows. 

Ray Medina Jr., a member of Los Diablos, fled the country years ago to avoid prosecution. Overseas, his wife by his side, he fights under the name CUDA. A name he took as an homage to his beloved‘71 Plymouth Barracuda. In the Latin world, the family name is part of your identity. So, when he gave it up, it only widened the gap between him and his father. 

Gang affiliations are for life, but sometimes, an athlete like Ray gets a leave of absence while pursuing their sport. But, “Once a Diablo, always a Diablo.” The gang he once ran with and the Mexican Cartel they are a part of want to cash in on his growing fame. They plan to reestablish his loyalty by having Ray mule money earned from their human trafficking operation back to the states. This act will reestablish his commitment to the gang, and they will hold it over him if he gets out of line. He refuses.

Still unaware of who arranged his first U.S. fight, Ray and Regina travel home. In Houston, Ray tries to reconnect with his father, a world champion in his own right who hung up his gloves after killing a man in the ring. Ray's father still runs the family gym, a constant reminder of what he had and lost.

His brother, still a member of the Diablos, is tasked with returning Ray to the gang. When he fails to deliver, they kidnap Ray's wife and blame it on their rival gang, the Southside Cobras. Their goal is to make Ray come to them for help. The plan fails. Ray's defiance leads to the death of his brother for not delivering his brother's loyalty. Angel the imprisoned psychopath leader of the Diablos, then calls for Ray and his father's death and orders Regina to be taken to El Jefe, the head of the Mexican cartel, as a peace offering for not delivering Ray as promised.

With time running out, Ray has no choice but to mend his relationship with his father, and together they take the fight to the Cartel. No rules; winner takes all.
