Grayson Rodgers looks like a common gardener, but guards a massive secret: for five years, he defeated five syndicate bosses, seizing the Golden Key—a symbol of power and access to their massive fortune. He seeks a quiet life with his wife. Before he can confess his identity, he finds his wife with Ivan, a high-ranking syndicate general who coerced Grayson into infiltrating the Golden Vault. Grayson must expose his true status while trapping Ivan, all while maintaining his gardener disguise.
