Find the movie 4 Hong Kong Policemen

Heavy Police Five people, A Dong, A Hao, A Jin, A Qi and A Fai, all serve in the police force, and they are still very good friends. Ah Hao was chased by people from underground banks after his identity was revealed during an undercover mission. He was injured and became paralyzed. The top police officials suspected that Ah Hao had betrayed him while undercover, so they refused to make any compensation and expelled Ah Hao from the police force. Ah Dong and the other four tried their best to fight to no avail. They lost confidence in the police and wanted to seek justice for Ah Hao and raise huge medical expenses. After careful planning, they decided to rob underground banks. ?

However, something unexpected happened, and this perfect plan went wrong. A Jin was accidentally recognized by the people in the bank, and a plan not to kill anyone turned into an act of murder and silence. Moreover, the money obtained from the bank was still not enough to pay Ah Hao's medical expenses and living expenses, so Ah Dong decided to wait for the opportunity to go out again. ?

After receiving the report, the police rushed to the underground bank and found that the bank robbery involved heavy firearms, so the police dispatched a special task force of the newly established Criminal Intelligence Division: "Heavy Police" to take charge of the case. The team consists of four people, including Zhou Cong, Sam, and Xiaozhen. They are good at heavy firearms and each has special skills. They are young and promising, smart and capable, and have become a new force in the police force. Zhou Cong led the team members to conduct in-depth investigations from various parties. From the clues, they found that the case was most likely carried out by police officers, and the finger was directed at Ah Jin. However, there was no conclusive evidence?

Zhou Cong concluded from various signs that A Dong and the other four would plan the next action. They followed the clues and discovered that A Dong and the others were engaged in a black gun deal. Zhou Cong led the "heavy police" brigade police officers to surround them, but A Dong cleverly avoided the pursuit. Zhou Cong was sure that they would commit crimes again. He sent a team to closely monitor the underground banks. Unexpectedly, Adong relied on the police's intuition to feel that Zhou Cong would definitely do this, so he robbed the deposit vehicle on the way to transport money in advance. Gunmen from the bank swarmed in. Zhou Cong used the evidence collected to find out where A Dong and others were hiding, and went to arrest them. A melee between police and criminals started on the road. During the melee, Archi was seriously injured, Ah Fai was captured by the bankers, and Adong was captured by Zhou Cong. Although Zhou Cong successfully solved the case and completed the task, he was very dissatisfied with the police superiors' attitude of giving up on Ah Hui and not saving him.

He decided to team up with A Dong and A Jin to go to the bank to rescue people. The other three members of the heavily armed police also joined the action. The bank instantly turned into a blazing battlefield. In the end, everyone successfully defeated the bank. A Dong handed the money to Ah Hao. Afterwards, he turned around and surrendered to Zhou Cong...
