Professional killer Bart (Eric Ng) is highly skilled, has many employers and earns a good income. He and his wife A Ling (Fong Chi Xuan) live in a high-end residential area and live a comfortable life. Unfortunately, the good times did not last long. After the financial crisis, the couple fell into a financial crisis. Bart was forced to kill for the rich wife, but the rich wife was demanding and asked Bart to film the killing process in addition to killing, so as to vent her hatred. Bart understood the principle of customer first and decided to find a partner to cooperate. By chance, Bart met director A Quan (Cheung Tat-ming) in a bar. The two hit it off and became a killer director duo. For a while, their business increased greatly, and a series of "hiring killers to shoot people" operations were launched. Later, the underworld boss Biao heard about it and decided to hire Bart and A Quan to kill the gang traitor Da Xiong on his behalf, and to shoot a video so that he could have real evidence to explain to the gang and secure his position as a steward. Will this hiring killer to shoot people succeed?
