This article intends to discuss the psychosis trigger considering the passage from its previous moment: pre-psychosis. It's possible to infer that the trigger can be avoided by an imaginary dual relation established by the individual preventing him from the outbreak. In order to examine the reasons present in the trigger of psychosis, I firstly used Lacan's reference about the crime of the Papin sisters published in his doctoral dissertation of Medicine (1932). Secondly, I selected parts of the film Sister my sister that portrays the crime and was based on the real facts. Finally, a hypothesis is proposed on the reasons for the psychosis trigger followed by additional references about Lacan's later theory focusing the matter of psychosis on the concept of Verwerfung (foreclosure).

Palabras clave : Pre-psychosis; Trigger; Imaginary dual relation; Foreclosure.
