此片由真实故事改编。讲诉一个毒贩被警察抓获,帮警察做任务来减少刑期。因为他的地域优势和才能,反犯罪集团决定任命他为卧底潜入一个威名远扬的摩托帮派——瓦格斯帮(Vagos)。在他潜入的过程中,必须经过一次又一次的伪装和打交道,才能在帮里调查出他们的底细。但在做任务的过程中,同时也在面临着危险....A gritty fact based drama series that tells the astonishing story of a drug dealer who was arrested then given a desperate ultimatum: serve over 20 years in jail, or go undercover inside one of America's most notorious biker gangs. Charles Falco opted to go undercover and for the next three years he led a crazy and dangerous life infiltrating the Vagos motorcycle gang, collecting evidence while faced with the constant risk that he might be discovered and become one of the gang's victims. Each episode unfolds a different step in Falco's covert investigation into their illegal activities, while across the series, the drama builds as carefully constructed character arcs unfold bitter personal rivalries. These tensions finally erupt when the gang's Vice President is killed in a motorcycle accident, unleashing a chain of unforeseen consequences that ultimately tear the gang apart. With suspicions about Falco's true identity mounting, the operation threatens to unravel, leading to a tense and dramatic conclusion. Drawing on the wealth of material from Falco's time under cover, along with broader documented historical research of inter gang rivalry, this series dramatically captures the reality of outlaw biker counter culture: a world where freedom is equated with the right to carry guns and trade drugs with impunity, and respect can be earned through fear... Following the conclusion of his undercover operation with the Vagos, the reformed Falco goes into witness protection... but hooked on the adrenaline rush of undercover work he volunteers to go undercover inside not just one, but two more biker gangs...
