When his ex-fiancée is murdered, Gunner vows to take vengeance on Los Angeles For more than a decade, private detective Aaron Gunner has regretted letting Nina Hillman go. They met on a city bus while he was on his way to the Los Angeles Coliseum for a football game, and by the time they were through talking he had long since missed kickoff. He proposed to her quickly, only to get cold feet and cancel the wedding. After less than a year, she married another man. Eleven years later, Gunner is still alone, and Nina's house is a crime scene.   The homicide detectives tell Gunner that Nina's husband has been abusing her for years. They assume that today he simply went too far. As he seeks justice for his long-lost love, Gunner uncovers a citywide chain of domestic abuse that he could have saved Nina from, had he been man enough to marry her. It's too late to protect her now. Revenge will have to do.
