The Second Woman (Chinese: 情谜; pinyin: Qing mi) is a 2012 Chinese-Hong Kong film directed by Carol Lai.

After hearing that Xiang performed better than her, Bao and Nan's relationship starts to deteriorate as she suspects that her twin sister and her lover might be carrying an affair behind her back.

Nan, though convinced that Xiang does often disappear without leaving a message, is extremely suspicious of Bao's lighthearted attitude about the whole situation.

Uncle Tai finds a floating jacket at the shore and reports it to the police; KK and Fan is convinced that Xiang drowned Bao at sea to take her place based on this evidence.

During one rehearsal, Amy is injured but Nan believes Bao caused the accident on purpose so that she could rise as the female lead.

KK and Fan reaches the conclusion that all this time, it was actually Bao, not Xiang disguised as her, who wanted to succeed in the troupe's live performance.

Accepting this, Xiang finally stabs herself to death with Nan crying over her body and Bao mourning at a distance as the crowd gives a roaring applause.
