"Moving Targets" was released in Mainland China under the title "Young Detective 青年干探" with an estimated box office gross of ¥3,000,000 RMB.

Cheung Wai-kit (Nicholas Tse) and Ngai Fung "Fit Lo" (Edison Chen) are best friends and two of Hong Kong's top young cops.

After foiling a robbery attempt they are promoted to the Narcotic units led by hot-headed police chief Cheung Tit-Man (Simon Yam).

Kit requests a transfer to the internal affairs department, but decides to participate in one last operation where the team tries to take down a major drug lord known as Big Bryan (Ken Tong).

To make things even more complicated Fit Lo is also married to Kit's former love interest and cousin Wing Chi (Gillian Chung).
