A nail-biting, hair-raising suspense yarn that feeds on jealousy, this chilling film by Hans Alfredson has John (Sverre Anker Ousdal), a philandering husband, fall in love with Clara (Malin Ek), a young poetess. When Clara and John move into an apartment on the sleazy side of town, neither her former lover nor his wife put up much objection. Then oddly menacing things start to happen in the apartment: objects are misplaced in a dangerous way, the gas leaks, and someone unknown is filling the place with graffiti. Clara's health degenerates rapidly, and as ominous circumstances push her and John to the brink, a shocking revelation looms ahead.
