The Innocent
Sean Black
When college basketball coach Malik Shaw disappears in the wake of a devastating family tragedy, his absence is initially dismissed as the collapse of a troubled former athlete. But private security specialist Ty Johnson senses that something far more dangerous is at work, and he and Ryan Lock set out to uncover the truth. Their investigation leads into a quiet Minnesota college town where buried secrets, institutional loyalties, and a chilling conspiracy of silence threaten to put them—and the missing man—in grave danger. A tense thriller about friendship, corruption, and the high cost of exposing hidden wrongdoing.
