Ling Feng (played by Julian Cheung) and his good friend Fan Yi (played by Wang Yangming) are both anti-drug police officers. They are good brothers who have been through thick and thin together. However, one day, news of Fan Yi's death came, and Ling Feng became the biggest suspect, and was also stigmatized for colluding with drug dealers. Ling Feng knew that he was the only one who could prove his innocence, so he decided to embark on a journey of escape. Jian Wenshan (played by Fiona Sit), who firmly believed that Ling Feng was guilty, chased him relentlessly. During the process of absconding, Ling Feng met a woman named Lin Yin, who provided him with convenience everywhere, but even so, Ling Feng's chance of proving his innocence was very slim. Just when he was desperate, Fan Yi showed up, and Ling Feng's crime disappeared, but the story did not end there, and a bigger trap was waiting for them.
