The kidnapping case of a 3-year-old child occurred in Thailand 12 years ago. The father was killed and the ransom of 20 million baht was taken from him, and the child, Tetskei Godai, never returned. Twelve years later, a fighter named Tetsu appears in the Muay Thai ring. He had no family and was forced to compete in grueling matches under the orders of his promoter, Chakrapat. Is he a philistine? When the match in Bangkok was finally scheduled and it seemed that Tetsu was close to entering the rankings, Chakrapat's treasured child Garchai appeared in front of Tetsu. He is an elite guaranteed Muay Thai champion. Tetsu was nothing more than a biting dog.
