Zazdena / Walled In (2009)(CZ)

On the day of her birthday, the young engineer Samantha "Sam" Walczak is assigned by her father to conduct a structural analysis of an eight-floor building. One hundred and twenty units are located in the middle of nowhere and require demolition. Sam finds four tenants, having received the eviction notice, but are still living in the building: the caretaker Mary and her teenage son Jimmy, Burnett and lady Denise. Mary lodges Sam in apartment 208, furnished as the former dwellers have never collected the furniture. Jimmy befriends Sam and advises certain "rules" to be adhered to. Sam is haunted during the nights by ghostly noises and discovers that the building has dreadful secrets. She investigates further and finds that the successful architect, Joseph Malestrazza, built the place following the principles of the Egyptian pyramids. Twelve years ago, one revengeful worker walled dwellers in, including Mary's beloved husband, entombing the victims in cement. Over time weird things happen to Sam and she believes that Jimmy might be playing a prank on her, until she finds out the shocking secret of Malestrazza and his building.
