In a very long eclipse of the sun, an unknown disease has been widespread. Ali is accused of the murder of Saman in a club and the police is going to stage a reconstruction of the murder.

The police take a young man to a crime scene, where he killed another young man. All looks quite simple and the police just needs to re-enact the murder and then close the file. However, the killer and his friends are all at the location and actually plan to commit murder again: they want to kill the twin sister of the murdered man. And their motive is more sinister than anyone would think.—Anonymous
