Los Angeles police detective Lt. Ohara, a contemplative but shrewd officer, watches as his colleagues bring in a man charged with a robbery-murder spree that included a cop killing. Going through witness statements, Ohara realizes that the wrong man was arrested and that the real killer is someone who very closely resembles him - but is left-handed while the suspect is right-handed. Ohara unloads his gun and secretly passes it to the suspect, who takes Ohara "hostage" and escapes. Ohara then stashes the suspect in his home and reports back to headquarters. The killer ...
Ohara and the others are protecting a witness who is suppose to testify against a criminal whom they've been trying to nail for years. But the man finds out where he is and kills him but a girl sees him. Ohara promises to protect her. He brings her to somewhere where he thinks she'll be safe but the man finds her. Ohara thinks there's a leak but has no time to find it. So he tries to protect as best he can.
Ohara captures a criminal. When it's learned he committed a crime in Japan, a Japanese cop named Toshi arrives to bring him to Japan to face trial. When they meet him; he is so full of hot air. When they are at the airport and about to leave, someone knocks him out and frees the criminal. He then reveals he's not the super cop he claims to be. He decides to stay and help recover the man cause he feels humiliated. Ohara tries to help come to terms with what happened.
Ohara and the police got two gangs to make peace. But when the former leader of one of the gangs, who was in prison, returns and was hoping to reclaim his crown. And when he hears of what happened, he takes a gun and shoots one of his gang's members. And it's touchy for Jesse, because he was once a member of the gang and he and the leader have history which Jesse tries to avoid.
