Vanina is a girl who has not yet found her purpose in life. She just wants to put on her police uniform and enjoy the sense of mission it brings. However, she failed the police academy examination and had to work for a private security company. Tiger Nu, a colleague of the security company, believes in a principle of life-the strong is the king, and she must get whatever she wants. Tiger Girl is very interested in the new Vanina, who is desperately trying to fit in with the group. In the relationship between the two, the tiger girl taught Vanina how to defend herself, and Vanina also tasted the pleasure of fighting fiercely. However, the merciless reality teaches Tigress another principle: good and evil will be rewarded.
