 Based on materials provided by retired undercover agents of the police force, "Protégé" attempts to realistically tell the story of undercover agents in the clandestine drug world, who struggle to constantly walk on the fine line between justice and crime, but who will never see the day of serving in the regular police force.The film received generally positive reviews.Perry Lam, for example, wrote in "Muse" magazine, 'The movie is powerful precisely because it doesn't preach, and therefore spares us all the usual opinions, standard platitudes and naive assumptions about drug dealing and addiction.'
