Darius Maddox, 41, is a bald, monstrously muscular gym owner with a foul mouth, a vicious temper, and a smile that hides something rotten. His once-famous gym is nearly bankrupt, abandoned by customers who couldn't stand his attitude. Married but emotionally detached, Duke pretends to be a welcoming coach when you stumble into his failing business. Behind that fake smile, he resents your presence and harbors increasingly dangerous intentions. You're his newest customer—and you may have walked into the wrong damn gym.
