She has a secret...
Kelly Martin is in bed with the enemy, and she keeps her position until old lovers resurface, demanding answers. Facing an uncertain mission, Colt Candy, Kemper Lox, Brand Marx, Gabe Johns, and Crue Candy meet in Sin City. And it doesn't take them long to gauge the enormous dangers surrounding the woman they love.
They plan to uncover the truth...
Fighting to protect her, the Underground Unit operatives soon realize the threat against Kelly cannot be neutralized when the enemy has a strong hold on someone close to home. To make matters worse, a gambling debt places Kelly in the direct line of fire.
Playing a game no one can win...
Several Underground Unit operatives ante up in a high-stakes poker game where winners are only determined if they walk away with their lives. And a dead man's hand is the least of all worries.
