During the hen night, Kiki  encounters a handsome photographer named Jack (Z.O.) and falls head over heels for him. The half drunk Kiki cannot resist having a one-night stand with him. At the same night, Sean encounters a girl named Bobo (Carol Yeung) during the night when he and his colleagues go to the nightclub on a police operation.
