Synopsis
The Hong Kong Police Force Traffic Branch is divided into two departments. The Enforcement and Control Unit（E&C）is in charge of enforcing traffic laws and arresting those who break them while the Accident Investigation Division (AI) investigates traffic related accidents. To Cheuk-fung (Kenny Wong) is the Inspector In-charge of the E&C Unit. His stern and cold appearance makes him an awkward character to work with and is also unapproachable to his subordinates, but his dedication and demand in his job also makes his family life non-existent. When the former Police Commissioner's daughter Bui Sam-jou (Sisley Choi), who everyone calls Bui Baby, is assigned to his unit and put under his supervision he is not afraid to lecture her when he thinks she has done wrong even though all other senior ranking officers are afraid to offend her due to respect for her father. Bui Baby is dedicated and, wanting to show her full potential, takes To Sir's comments seriously to improve herself. After seeing Bui Baby's passion and commitment to her job, and her being the only one not afraid to approach him when he is down, the two form a mentor and protege relationship.

To Sir's other problems are his former subordinate Sze Ma (Benjamin Yuen) has just been promoted to Inspector in the AI division. Sze Ma's odd behavior often is misunderstood and offends other people. Due to his behavior the E&C team thinks he has forgotten about them now that he is with AI, causing a slight rivalry between the two divisions.

However Sze Ma is also very dedicated to his job and often only sleeps a few hours a day while trying to solve cases. It also makes his life non-social which results to him talking to a toy basketball he named Jason as if it was a real person. He notices that his new subordinate Yiu Yiu (Natalie Tong) who has been a dedicated officer with a great reputation for her photographic memory, no longer gives her full potential at work and always leaves on time due to the haunting memory of her parents' deaths. Wanting to help her get past the tragedy and to push her to her former self, Sze Ma uses odd tactics that end up offending her. Yiu Yiu, who can't stand Sze Ma, doesn't know that he has fallen in love with her while working closely with her, with even Sze Ma himself scared of these feelings at first since Yiu Yiu doesn't fit his usual tall and long leg type.

Cases
When a delivery truck carrying illegal fireworks rear ends a bridal car it is assumed that the delivery truck caused the accident but with evidence showing the delivery truck's windshield was struck by an unknown object causing the accident, newly promoted AI Inspector Sze Ma Sir must try to solve who really caused the accident. The Best Man driving the bridal car claims the delivery truck crashed into him but testimony from the truck drivers claimed an object struck their windshield and that the bridal car was swiveling right and left on the road. On her first day at E&C, Bui Sam-jou is assigned to go undercover and ticket bus drivers who do not comply with the law. When she unreasonably tickets a driver with a total of 8 tickets, the driver does the extreme by drinking energy drinks in order to work extra shifts to pay off the tickets. Bui Baby happens to be a regular passenger on the same bus driver vehicle during one of these extreme shifts and witnessed the occurrence of an accident. She sees the driver of the private car acting unusual and also the bus driver falling asleep at the wheel. When the bus driver is charged with vehicular homicide, Bui Baby does her best to remember every detail and keeps recanting her statement. Her eagerness to clear the bus driver causes her to offend the AI team and Sze Ma Sir in front of high-ranking officials. To Sir's former subordinate in Narcotics Bureau and protege Wing Tak-him has been taunting traffic officers by dangerously speeding in traffic. To Sir tries to bring down Tak-him who is now a drug trafficker but doing so reopens the past that could hurt his career. Madam So's late husband Au Suen-wai was also a subordinate under To Sir in Narcotics Bureau, however Suen-wai's gambling addiction got him entangled with Tak-him illegal dealings and ultimately caused his death. In order to cover Suen-wai illegal activities, To Sir lied to let him die honorably. To avenge for the past, Tak-him uses conversations he recorded with Suen-wai to blackmail To Sir and then tries to kill To Sir's son, but Tak-him's rash behavior gets him in trouble with the triad community when he steals another gangs drug shipment. To escape Hong Kong he holds To Sir's son hostage in order to force To Sir's wife into helping him escape. Concert tickets for Korean girl group Amazing Girls has become so sought after that Bui Baby and Tai Gwan find a middle aged taxi lady and a young man on a motor bike fighting about tickets on the street. Later the taxi lady and young man get involve in a traffic accident and the young man eventually dies from his injuries. The taxi lady is charged with murder but Yiu Yiu believes she is innocent due to the taxi lady's interest with a particular member of the Amazing Girls and tries to convince Sze Ma Sir that she is right. Sze Ma Sir who only believes in data does not succumb to Yiu Yiu's reasons and continues using his odd way to solve the case. Eventually on the day of the Amazing Girls concert they all find out the true culprit behind the accident and it's the person with the concert tickets in their hand. An elderly lady with no identification on her is involved in a hit and run that leaves her in a coma. The driver who crashed into the elderly lady states that a Sky Rover van was driving towards him at high speeds and in order to avoid it he accidentally crashed into the elderly lady, but with no other witnesses the AI team must find out if he is telling the truth. With only a key found on the elderly lady and no one filing a missing person report, the AI team has the daunting task of finding out what the key unlocks and who she is. Short on staff with no one wanting to take on this task, Sze Ma Sir ask if the E&C team can lend them a person. To Sir agrees but lends the AI team his most unskilled team member which is Bui Baby. Bui Baby's dedication to the task helps the AI team solve the mystery of the elderly lady's identity within days and also solve how the entire accident happen when she spends her personal time finding out if the Sky Rover van exist. The AI team has a hit and run case that should be easily solved since a few surveillance cameras captured only the victim and suspect at the accident scene but not how it happened. However, due to the recent rain storm any other evidence has been washed away from the accident scene and also the suspect has a high powered attorney who is also his brother protecting him. To determine how the accident happened Sze Ma must reconstruct it with the expensive sports car the suspect was driving. Since the suspect is unwilling to lend his sports car to the police Sze Ma resorts to asking the only other person in Hong Kong that has the same exact sports car, which is his on and off girlfriend Pearl's other boyfriend. Dangerous criminal Hung Fan's wife Chui Ying, who is also a wanted criminal herself, is planning to break him out of prison on the day of his trial. With the help of Hung Fan's sworn brother Hung Yan, who is impersonating as a reporter doing a story on Bui Baby, he uses his newfound friendship with Bui Baby to get close to her in order to exact revenge for Hung Fan's imprisonment, which Bui Baby helped with capturing. Besides revenge Hung Yan also bugs Bui Baby in order to stay one step ahead of the authorize to facilitate his brother's escape.
