Fu Qin disliked the greasy chicken soup sent by his neighbor Aunt Qin, so he fed it all to stray cats. Unexpectedly, the cats grew into three hundred kilograms of extinct South China white tigers in one year. After calling the police, experts revealed the truth. Aunt Qin relied on evil recipes passed down from her ancestors to raise ferocious beasts. The police captured Aunt Qin and destroyed the underground workshop. Fu Qin was hired by the conservation center for his meritorious service in protecting tigers. He and a team of experts went deep into dangerous areas to find the antidote, successfully helped the white tigers get rid of their drug addiction, and started a new life of protecting rare white tigers.
