Veteran Wang Gufeng just wanted to open a cafe in a small town in the south of the Yangtze River to bury the memories of the war. However, a cup of "tactical mud coffee" made him offend Lin Xiaoyou, the hard-spoken and soft-hearted flower shop owner. I thought the years would be peaceful, but Zhou Xiao, his former betrayal comrade-in-arms, came back with the underworld, and under the guise of "urban renewal", they pressed hard to seize his ancestral property and shop. Faced with conspiracy traps and undercurrents on the streets, Gu Feng no longer holds back. He has coffee in his left hand and a knife in his right hand, from stalking gangsters to joint neighborhood merchants, vowing to tear apart the disguise of darkness. When the tenderness of a tough man meets the toughness of flowers, this battle for protection is not only a passionate collision of fists and feet, but also the mutual healing of two lonely souls. Let's see how the retired soldier king creates a peaceful world amidst the fireworks in the small town, letting all those who covet it understand: veterans are not dead, but they are more difficult to mess with!
