"The Last Shot" tells the story of the Nationalist government's policy of "pacifying the country before resisting foreign aggression". The Central Bureau of Investigation ordered the arrest of a CCP undercover agent "Lone Wolf" who was very deep and powerful in Hongcheng. The two sides fought wits and courage, step by step. In the end, Chen Hui, the second son of the Chen family, code-named "Lone Wolf", played by Liu Jun, accidentally exposed his identity to save his younger brother and was killed. His third brother Chen Ze (played by Bao Jianfeng) inherited his second brother's unfinished revolutionary beliefs and embarked on the road of fighting against his eldest brother Chen En, who was a senior member of the Central Bureau of Investigation and loyal to the Nationalist government, and the traitor who betrayed his brother. The whole play is full of suspense elements. The deeply hidden disguises and carefully laid out conspiracies will be disintegrated by the protagonist's last shot.
