Bullet Brain

Born KO TAI-HEI, Detective COLUMBO has an IQ of up to 283, and is able to achieve a detection rate as high as 99%. Despite his outstanding credentials, he is labeled as a dangerous and combative figure that needs to be kept under watch. COLUMBO has launched a massive dragnet for three suspected kidnappers of a comprador. Having learnt from his subordinate PAU PING-ON that the crime scene has been brought under control, COLUMBO starts eating and drinking inside a tent. ROBINSON is taken hostage by one of the kidnappers and later gets shot by COLUMBO in the confusion. Fuelled with anger, ON blames COLUMBO for being too unscrupulous with everything he does. During their conversation, ON keeps addressing COLUMBO as “HEI”. Superintendent SCOTT is COLUMBO’s supervisor and has long been a thorn in his flesh……

Flashbacks: LOUIS reveals to HEI how he got to know his father KO NGAU. Now that NGAU has passed away, LOUIS needs ON to help arrange a final meeting for HEI and his late father. With the help of LOUIS, HEI has not only acquired permanent residence in Hong Kong but is also sent to the Police Academy for a series of training sessions. Unfortunately HEI has failed in all subjects and the then Academy Principal SCOTT is going to kick him out of the school soonish. Knowing that HEI will be expelled from the Police Academy for his poor performance, ON notifies LOUIS at once and LOUIS is kind enough to intercede for HEI. ON’s wife and mother are caught in a fire, but they just get rescued by HEI in the nick of time. ON has regarded HEI as a member of his family ever since then……

A senior officer orders LUNG to engage in a fencing duel with EVA, and LUNG manages to defeat the girl in just a few seconds. EVA comes to see LUNG as his supervisor and asks him to follow her instructions in all circumstances. EVA would like to see COLUMBO, but ON comes up instead explaining that COLUMBO is busy dealing with a tough case, which is also the biggest drug case in Hong Kong’s history. As EVA is almost frightened to death by a swarm of cockroaches inside the warehouse, COLUMBO shows up and comes to her rescue. COLUMBO explains to the journalists that the whole operation is led by EVA, which causes EVA to make quite an impression on him. Though becoming more and more annoyed with COLUMBO, ON believes that this man still has a conscience and he is still looking forward to his reunion with the original HEI……

ON is shocked to see COLUMBO break down crying with the china doll in his hand. The headache-stricken COLUMBO asks for an urgent brain operation in order to transform back into his original self. At his request, ON sends COLUMBO to the hospital at once. Fearing that the surgery might go wrong in one way or another, COLUMBO pleads with ON to write a letter to MUI to let her know that the china doll has already been repaired. LOUIS asks ON to look for COLUMBO, but instead of following the instructions, ON hands him a resignation letter on behalf of the renowned detective. In the meantime, LOUIS gets a long-distance call from the Hong Kong Governor who is currently on duty in London. LUNG visits his mother’s grave on the anniversary of her death, during which he takes a vow never to engage in gambling and bribery as his father CHOI TIN did in the past. LUNG is surprised to hear that TIN will be working with him in the same office……

ON is awakened by the baby’s crying in the early morning. With no better alternatives, he decides to bring the baby back to the police station. Manager WONG and his wife are shocked to see their son in the police station. Surprised yet happy, the couple grab back the baby at once. To avoid any possible trouble, ON claims to have found the baby outside the police station. ON finds COLUMBO so annoying that he cannot stand him anymore. COLUMBO shows ON a remittance receipt claiming that he has sent HK$500,000 to his wife in the UK. Not wanting ON to cause him any trouble, COLUMBO urges him to leave Hong Kong as soon as possible. ON takes out the china doll, but to his great surprise, COLUMBO grabs it and throws it onto the floor without a second thought. COLUMBO pretends to be so concerned about EVA’s relationship with LOUIS, as if he is most reluctant to see her argue with her father only for his sake……

COLUMBO manages to attract much attention and praise from EVA. EVA is keen to find out more about the china doll, so COLUMBO starts to spill the beans about his past with MUI. SCOTT asks LUNG to put a listening device inside COLUMBO’s office for eavesdropping purposes, but is rejected. LUNG finally decides to move to TIN’s place, giving COLUMBO a perfect excuse to pay them a visit. While visiting the CHOIs, COLUMBO manages to hide a listening device inside their living room. Curious about how COLUMBO got shot three years ago, EVA asks LUNG to accompany her to the scene for a thorough investigation on his new appointment as a CID Officer. LUNG and EVA enter a shabby hut in the neighborhood, shortly after which a suspicious-looking man suddenly pops up from nowhere. EVA runs out to catch the man but is knocked unconscious during their fight. LUNG tries to resuscitate EVA but is mistakenly thought to be sexually assaulting her……

COLUMBO asks EVA to stop investigating his case, as it would be too dangerous for her. LUNG hears TIN calling for help upon his return home. EVA hopes COLUMBO will find his Miss Right sooner or later, and suggests him join the upcoming Police Banquet so as to widen his social circle. ON’s wife JOANNA shows up in the banquet, and reveals to EVA how COLUMBO risked his life to save her and her mother-in-law a couple of years ago. Not wanting EVA to get cheated, ON is going to reveal the sordid truth behind the hypocritical mask of COLUMBO, but is stopped in the nick of time. COLUMBO forbids ON to say anything against him as ON owes him a huge debt that can never be repaid. ON goes through his old photos and recalls all the happy times he shared with HEI and JOANNA. ON gets into a church and prays to Our Lady asking for the return of the good-natured HEI. He is even prepared to give his life to fulfill his wish for HEI……

JOANNA can tell from EVA’s response that she is in love with COLUMBO. Much excited about EVA’s romance with COLUMBO, JOANNA describes the super detective as a loyal gentleman. But when she suspects ON being a secret admirer of EVA, her mood turns unexpectedly downbeat. LOUIS is shocked to hear that ON and COLUMBO have sustained life-threatening injuries and are both being treated in hospital. Director LI points out to LOUIS that ON and COLUMBO are so severely injured that they have just a slim chance of survival. Desperate to find out what has happened between ON and COLUMBO, EVA offers to lead the investigation into the incident. MUI has kept a huge pile of news clips about COLUMBO and the various cases he has solved. She seems to have deep respect for COLUMBO while bearing a noticeable resentment towards EVA. MUI runs into EVA inside the hospital lift……

EVA confides to COLUMBO’s body, during which the heart machine is found to be working again. Shocked yet happy, EVA rushes out to look for the doctor at once. EVA notices a kiss mark on COLUMBO’s face. Curious about who has come to see COLUMBO, EVA goes out to have a look, and finally manages to locate MUI down the stairway. EVA tries to seek LOUIS’ permission to transplant COLUMBO’s brain cells into ON’s body. JOANNA is so desperate to save ON that she even goes down on her knees and pleads with LOUIS. Touched by her persistence, LOUIS finally gives in and agrees to her request. Now that his condition is becoming stable, ON is placed in the same ward with COLUMBO. COLUMBO has been in a coma for a month, during which thefts have become increasingly rampant across the city. LOUIS needs SCOTT to rectify the situation as soon as possible, and SCOTT too starts putting pressure on EVA. JOANNA decides to go back to England……

SCOTT claims to have caught the perpetrator of the acid attack, but EVA believes that the so-called suspect SHE PING is just a scapegoat for the real culprit. EVA receives a letter from JOANNA stating that she is not coming back to Hong Kong and asking EVA to look after ON. LOUIS needs LUNG to have a jog with him, during which he encourages the lad to woo EVA. MUI reads in the newspapers that COLUMBO has woken up from coma. Later she arrives at the police station with a big bowl of soup, and introduces herself as the wife of COLUMBO. TIN brings MUI to EVA’s office. Knowing that MUI used to have an intimate relationship with COLUMBO, EVA shows open hostility to her. The two ladies begin to run out of conversation after a bitter quarrel. A woman is reportedly trying to jump off a building to kill herself, so LUNG and EVA hurry to the scene to have a look……

TIN points out that LUNG and EVA are worlds apart in family background and social status, and suggests the lad go out with HAN instead. As arranged by LUNG, the real estate broker who is responsible for the transaction between MING and MUI has come to the police station to give a statement. Having studied the real estate broker’s statement carefully, EVA believes that MUI must have something to do with MING’s disappearance. As soon as she opens the door, the messy-haired MUI is shocked to see EVA waiting outside her apartment. EVA asks MUI a series of questions, following which she urges LUNG to search her place, but is rejected. In response to EVA’s endless questioning, MUI reluctantly reveals how she was forced to become a prostitute when she was younger. Feeling insulted and humiliated, MUI starts weeping. Knowing that COLUMBO has mysteriously disappeared, LOUIS and EVA rush to the hospital to see what is going on……

EVA accompanies COLUMBO back to his place, during which she plucks up the courage to confide in him. Sadly COLUMBO is totally clueless as to what she is talking about. Believing that the china doll may help bring back his memories, EVA decides to give it a try and takes COLUMBO into his own bedroom. Without any identity documents with her, MUI remains in a coma after the car crash. LOUIS suggests sending COLUMBO back to the hospital at once, but EVA insists on keeping him at home as this will make recovery so much easier. She herself is going to stay with COLUMBO so that she can look after him in a home environment. LUNG offers to help EVA, and the pair get on really well with COLUMBO. The three of them are so close that they even go jogging together. Director LI points out that COLUMBO is recovering well and is fit enough to undergo a medical assessment……
