On the First Beat (Traditional Chinese: 學警出更) is a TVB modern action series broadcast in June 2007.

The story continues on with the two male leads in the series with their growth as young police officers with personal conflicts in their bonds as friends and romantic relationships.

After going through the excruciating training of the academy, Chung Lap Man (Ron Ng) and Lee Pak Kiu (Sammul Chan) finally become official police officers and are assigned into the same branch.

Newly appointed police Sergeant Cheung Ging Fung (Michael Tao Dai Yue) turns out to be the crime leader of that operation.

The feelings between Man and his colleague Cheung Nim Yan (Joey Yung Jo Yi) gradually develop.

Chung Lap-Man (Ron Ng) and Lee Pak-Kiu (Sammul Chan) patrolling the streets of Hong Kong with fellow senior constables.

During one patrolling shift, Pak Kiu messes with the wrong group of gangs, Cheng Chi-Keung (Wai Ka Hung) and Cheung King-Fung (Michael Tao).

Fiona and Lap-Man finds Chi-Keung and King-Fung dealing drugs in a parking lot and tries to photograph their drugs-transaction.

King Fung's sister, Cheung Nim-Yan (Joey Yung), who is an investigation constable, discover the fake letter prank.

During this time, Pak Kiu tries to take some psychology classes to try to build up a better resume when he applies for an inspector position within the police department.

Yuen Wai-Nei (Sonija Kwok) joins Pak Kiu's classes as she thinks its beneficial to police officers.

King-Fung, Ming-Cheung, and a few other sergeants receive a letter that tells them they will be training for the Police Tactical Unit (PTU).

Wai-Nei ends up hospitalised and severely injured, and Chi-Keung heads to the hospital to deal with King-Fung.

For the sake of Wai-Nei, King-Fung decides to lead life happily and take good care of their son, Kai-On.

Several of the previous characters had unresolved plot lines, but the actors had different committed projects and so they were never re-visited or had brief returns.

While badly injured, she had surgery and wasn't placed in the Intensive Care Unit or rigged to any medical electronics to monitor her poor progress.
