In 2003, "PTU" reversed the tip of Kowloon East to find Fat Sha's lost gun, and Johnnie To's stern style redefined Hong Kong police crime films overnight. In 2008, he gathered the original cast again, with Simon Yam, Maggie Shiu, and Lam Suet back in action. The closed-circuit television revealed that the case involving a suspected member of the triad wearing a blue hat made the team uneasy, and the issues of right and wrong became blurred, leading to the questioning of police officers' debt and gun problems once again. This time, Johnnie To stepped back as a producer, leaving his disciple, Law Wing-cheong, to lead the investigation into the case, firing the first shot for the sequel of "PTU", "Mobile Unit". There will be units from Raymond Wong and Ng Yiu-kwan coming up soon.
Within the police force, there is an invisible competition; among comrades, are they friends or enemies?
Hua (Simon Yam) and Maggie (Maggie Shiu) respectively lead their subordinates on a sudden mission on the last day before the team disbands: to search for the armed bandits who have infiltrated deep into the mountains. Since cooperating and leading the team for a year and a half, Hua and Maggie have been competing and arguing, causing the team relationship to split and become rigid. Maggie's team received praise from their superiors and got promoted, while Hua's promotion hopes were dashed.
While searching for the bandits in the deep mountains, the two groups separately searched and triggered attacks from the bandits. Hua and Maggie face a severe test in saving their comrades. How will they set aside their prejudices and work together to complete the task?... http://www.qvod.me/
