The movie revolves around the central character Xiaonian Zhong (played by Xu Zheng), an ambitious business tycoon who becomes the target of a mysterious man who imprisons him in a house.
The story begins with Zhong attending a business meeting where he clashes with a colleague over a major deal. The next moment, he finds himself waking up in a strange house, with no way out. A faceless kidnapper identifies himself as the "Falcon", and reveals that Zhong's imprisonment is punishment for his corrupt business practices.
The Falcon gives Zhong an ultimatum- he must choose between two doors (A and B), and each door will reveal a secret that he has been keeping from his family, friends, and business associates. Zhong must share the secret with the world via social media, or face dire consequences.

Trapped, and with no idea of the Falcon's true identity or motive, Zhong must race against time to escape from the house, uncover the truth, and clear his name. The movie keeps the viewers hooked with suspenseful twists and turns, and a thrilling climax that delivers on its promise.
