重要場景解說‍

電影中，黃警司率領警方從對面的一幢唐樓追蹤黑幫老大韓琛的行動，試圖緝捕毒販。與此同時，警方臥底／黑幫成員陳永仁以摩斯密碼向黃警司傳遞真實交易地點，而黑幫臥底／警察劉健明則提示韓琛警方即將到來。我們勾畫出兩個陣營的位置及傳遞情報的過程，幫助觀眾理解劇情。

Key Scene Explanation‍

In the film, Superintendent Wong led the police in tracking triad boss Hon Sam from a Tong Lau across the street, attempting to intercept the drug dealers. At the same time, police undercover agent Chan Wing-yan, embedded within the triads, used Morse code to relay the actual deal location to Wong; Triad mole Lau Kin-ming, embedded in the police force, informed Hon Sam about the impending raid. We visualize the positions of both sides and the exchange of intelligence, helping the audience better understand the plot.
