It's 1991, the early morning hours in a small port town where we come across a woman crying softly in the corner of a bar. Ex-detective, Daisuke Nango, and his simpleminded uncle, Shozo Akita, better known as Sho-san, arrive at the bar. It was Nango's fling with a Yakuza's girlfriend that brought on an early retirement from the police force for this smooth-talking, clever cop. Now, he's trying to make a name for himself in show business as "the singing cop."
Sho-san's offer of help to the distraught woman marks the start of a risky business, The "Trouble-shooters", men slightly left of law and order and dedicated to helping others out of tight spots. The woman's son has fled from the Yakuza gang he belonged to with some 10 million yen, (approx. $85,000) in cash. Nango's quick wit and sharp tongue resolves the problem and he somehow manages to turn the tables and have all the Yakuza bowing to him as he leaves their office. The next day, a young Yakuza who witnessed the expertise of Nango the night before, is down on his knees begging to become Nango's disciple.
One week later in Tokyo, Nango can be seen in front of a run-down, confiscated building putting up a sign for his new found company, "Trouble-shooters."
The first formal case is a single mother who cannot control her drug addicted teenage son. Nango's usual method of hard-mouthing and physical violence ends up getting out of hand, with him roughing up the mother as well, and getting a nasty crack to the head for his trouble.
Next, "The Trouble-Shooters" find themselves hunting down a rapist for the Godfather of the Higashiyama Yakuza organization. Koran, a beautiful Asian bar girl, describes a series of rapes which have targeted foreign women in a salon she works at, a carousing spot regularly frequented by the Higashiyama Yakuza family. The rapist doesn't only rape the women, he further humiliates them by shaving their heads and their private parts. What Nango eventually learns about the underworld and himself is shocking.
