After the meritorious police dog Lei Lei was retired, he was forced to live a retirement life of chewing cans and catching wild cats. Until one day, his trainer Li Fan, covered in blood, ran into the garage late at night: "Old man, the police station is full of ghosts!"
In order to track down the man behind the murder of his comrades, Lei Lei had to put on a "mad dog" mask and return to the police station. It pretended to chase the tail and knocked over the deputy director's cigar, bit the heels of the female forensic doctor, and even turned the anti-narcotics captain's office into a garbage dump. Everyone thought this old dog was crazy, but they didn't know that it was using its nose to decode lies: the Cuban spices in the ash, the special clay on the soles, the honeycomb patterns on the monitoring equipment...
When the truth pointed to the top-level "Hive Project", Lei Lei tore open his blood-stained fur in the explosion, revealing the last badge hidden by Li Fan: "The barking is for you, silence is my answer."
Mind-opening and exciting
