While serving in the bathhouse, a conflict broke out between the wealthy second-generation Xiao Xian (Peng Yuchang) and the sauna worker Zhou Donghai (Qiao Shan). Xiao Xiang was hospitalized in a parachute accident and his memory was lost. Zhou Donghai met him by chance and made a plan. He tricked Xiao Xiang into becoming his younger brother and lured him into working as a scrubber. The wealthy second generation embarked on a ludicrous bathing career.
