Chut!.

A young couple, Ines and Fred, have just moved into an apartment with a long corridor. After a few days, Ines hears strange noises and thinks she sees something. Trying to find out more, she gets scratched, but she doesn't know by whom or by what. Fred sees nothing and hears nothing. A tension arises between the two young people who do not understand each other. Is Ines going crazy or is it Fred who refuses to face reality?
