Before the DEA, there was UNDO-the United Narcotic Deployment Operation. This agency's primary assignment was to monitor and infiltrate the Colombian drug cartel. And when Internal Affairs suggests Matt Stryker as a possible candidate for the newly formed agency, he doesn't hesitate in accepting the position. Little does he know just what he's getting himself into.
Stryker goes deep undercover in Miami, penetrating a powerful and dangerous organization headed by one of Colombia's most ruthless drug lords, Gonzalo.
