Agnes and Qing are Hong Kong's representative rhythmic swimming athletes. They have swept the pairs event awards since childhood. Unexpectedly, an epidemic brought the world to a standstill and caused a sudden change in their relationship. Agnes found that she had different emotions and could not get rid of the desire for Qing's body. To escape her desire, she even had sex with her pursuer Amin. As her life becomes more chaotic, she is deprived of her qualifications for the main election. Watching Qing practice a pas de deux with others, Agnes becomes jealous and discovers that she not only did not love Amin, she didn't enjoy sex with him. Agnes returned to practice, hoping to regain her body pride, but without a swimming pool and close friends, she couldn't dance the pas de deux. When they were unable to jump down, Qing appeared like a gift, and the two climbed into the pool without water.
