Lights alliance to Ed Romeo, his new boxing mentor comes between him and his family. Although, Romeo likes Teresa and the girls, he wants Lights to cut his father and brother out because he thinks they are weighting him down. This does not sit well with Lights, who in return, tells Romeo he doess not feel free of them, but feels controlled by him and decides to free himself of his eccentric trainer. Meanwhile, at the gym, Johnny and Romeo get into a fight, which ends up in an unfortunate accident for Lights.

After being accidentally stabbed with scissors by Johnny, Lights' injury puts his comeback, his health and Theresa's medical career in jeopardy, especially when Barry Word can not postpone the fight because of the penalty fees. As his family's expenses pile up, Lights tries to speed up the healing process by secretly seeing a doctor to give him a potent "medicine cocktail" mixed with prednisone. Lights tries to recover from his unfortunate injury, but finds out from Mike Foster—now a TV reporter—that Word is already setting up Reynolds' next fight with a Ukrainian Muslim boxer named Mustafa. Meanwhile, Lights and Johnny find out that Margaret is seeing gangster Hal Brennan, and think he is playing her to get closer to Light's and backing his fight.

After all the trials and tribulations that led up to the championship fight, Lights goes to "war" when he finally faces off with "Death Row" Reynolds for the heavyweight title. Before the big fight, Hal Brennan gathers all the former champs that have been burned by Barry Word and starts a war against him by starting a new boxing alliance called United Boxers. But in order for Lights to be a part of it, he suggests a 10 percent cut for a health fund to help all the boxers in need of medical care. Meanwhile, Word has a pre-fight talk with Lights, and it is not very inspiring the night before the fight. Theresa has her own talk with Reynold's wife, Jennifer. As soon as the third round begins, Lights manages to K.O. Reynolds and wins back his title, but suffers a severe concussion. After the fight Theresa makes a shocking discovery about Lights: she goes to his side and watches in horror as he groggily asks her "Who won?".
