The year 2019 marks the 175th anniversary of the Hong Kong Police Force. The Force has partnered with the Television Broadcasts Limited for the first time to produce a television movie entitled "PTU 2019". Unlike other police movies, this television movie covers the training of officers of the Police Tactical Unit (PTU) as well as their work and inner world to let the audience learn more about their lives.

The Force has arranged officers from various units to explain their daily work and use of equipment to the crew in the production process. The Force also provided a real working environment for the shooting. Details were thoughtful such as showing the crew how to fix a beret to enhance the realism of the movie.

The PTU is known for its stringent and rigorous training, but very few know about the "Stone Pavilion" in the PTU training base. It is a place that serves like an oasis for the officers to relax a little. It is featured in the movie with actors enjoying afternoon tea and a little chit chat there before getting back to duties.

Police work involves not only cases of gunshots but more cases of human touch, such as those relating to domestic violence and missing persons. If the cases resemble their personal lives, the officers may have deeper feelings.

Earlier, a mother dumped her baby daughter's dead body, and PTU officers were tasked to locate the body in a landfill. This case was featured in the movie.  Sisley Choi, who played the role of a PTU officer, quarrelled with her boyfriend over the issue of getting married and having children. She was called to work on this case in the landfill, which triggered her to rethink the meaning of life and gain a new perspective of life.

Non-heroic, non-gunfire, this movie puts the audience in the shoes of frontline officers so that the public will learn more about the real work and inner world of police officers.
