When you’re an undercover police officer nobody knows who you really are–not your family, your co-workers or your marks. And sometimes you even lose track of who you are yourself. This special tells the real stories of dangerous undercover police work through the real video and audio recordings of the officers in the moment as well as interviews with the people closest to the action. It’s a riveting glimpse into a world rarely seen or heard–one wrong move and years of work go down the drain and the suspect gets away with something horrific.
