Fai Seung Dat Yin plot
After robbing a jewelry store, amateur criminal Collins takes refuge in an abandoned apartment building. Coincidentally, this is also the hiding place of serious criminals who are armed to the teeth. They shoot their way out, killing a number of police officers. Collins is arrested and the police scramble to find the criminals. Ken and Sam have been a detective duo for years and are expected to solve this case as well. However, it turns out not to be as easy as it seemed. Meanwhile, they also have their own private problems. Mandy is very much in love with Ken, but he is too busy with his work and pays little attention to her. Sam, on the other hand, also has a crush on Mandy, but has to be careful because the focus on his work and the business on the streets wanes.
