After a teenager dies from taking a seemingly harmless pill, Quincy sets out to shut down the highly dangerous, but legal, trade in ‘look-alike' drugs. He tries to find out why it is legal to make such pills and concentrates on closing down a small, local shop that sells the pills.

Michael Moroshima, a cop working undercover with the Asian task force and Sam's best friend, is killed while listening in on a deal between the Yakuza and the Mafia. Sam explains to Quincy all about the Yakuza and the Japanese code of honor that means his friend's father will try to find his son's killer and exact revenge. Sam tries to prevent this from happening but finds himself getting into deeper trouble himself.
