Description：Qi Mei (played by Jia Jia), Danni (played by Du Xiaomi) and Nai Qing (played by Wang Yansu) are three girls with different professions. They work in a building, but they don't know each other. Because they are very unhappy with their work in their respective units, they coincidentally go to the disco to vent their depression. The three girls who don't dance and don't know each other lament that people's hearts are not ancient and things are impermanent. By telling each other about their experiences, the girls reached a consensus in their minds. They decided not to bow to evil and jointly challenged the bad boss. They made careful arrangements. Qi Mei's "water snake waist" who often bullied her in her unit was hit hard for the first time. Danni, who was harassed by salty hands, finally got rid of the bad temper in her heart, and the "crooked glasses" who were against Nai Qing everywhere also received the punishment they deserved. Just as the girls toasted to celebrate the victory, three dirty "unlucky guys" waited for an opportunity to retaliate.
