Yadang The Snitch

Kang-soo is wrongfully arrested on drug charges. After being convicted, Prosecutor Koo throws him a lifeline by turning him into an informant, infiltrating the ranks of drug dealers and addicts and providing the police with information in exchange for a reduced sentence. Kang-soo quickly proves his talent and becomes a star in the field. As he becomes more involved, he realizes he is just a small pawn in a game where the filth of the drug world mixes with the corruption of law enforcement and the mire of politics.
