Dave Atwell was a regular suburban Canadian kid who rose to the heights of society, rubbing elbows with billionaires as a personal security specialist before getting involved with some of the country's most notorious gangsters as a member of first the Para-Dice Riders and then the Hells Angels. He was sergeant at arms for Toronto's notorious downtown chapter of the Hells Angels, and he saw it all: the drug trafficking, the violence and the structure of the organization. First his involvement with the gang cost him his career in personal security, and then it threatened to cost him everything. Atwell opted to work with the police, becoming the highest-ranking Hells Angel in history to cooperate with law enforcement. Atwell reported the Hells Angels' activities to law enforcement. Atwell retraces his days living a dual life as biker and informant, surrounded by major drug trafficking and the violent, paranoid and increasing suspicious bikers who stood to lose their livelihoods and potentially their freedom unless they found the rat they knew was hidden in their midst.
