In 1936 China, a nearly bankrupt drama troupe starts performing in a burned-out theater where the great actor Song Danping was killed. One of the actors, Wei Qing, starts seeing strange apparitions that could revive his troupe and deliver him to the same fate as Song Danping.

A disfigured musical genius roams a traditional Chinese opera house, punishing those who offend him.

Jiang Danping arrives in a city at night, where often a mysterious man causes panic.

In this Chinese version of The Phantom of the Opera, the mysterious Song Danping terrorizes the newly rebuilt opera house and its young star.

Essentially an adaptation of Gaston Leroux's classic The Phantom of the Opera, Mid-Nightmare is set in a Huangmei diao teahouse theatre, which an embittered and horribly disfigured ex-performer ‘haunts', looking to extract revenge on his enemies and falling in love with a talented and beautiful, but ultimately unattainable, ingénue.
