Having grown up under the controlling grip of her fame-hungry mother, Janet Slate jumps at the opportunity to move into what looks to be a great high-rise apartment in downtown Detroit. Yet some deals are too good to be true, and one night her boyfriend Mark finds her in the middle of the street, having fallen from the balcony thirteen stories above. In order to investigate her death, Janet's sister Lara moves into the same apartment and soon encounters odd neighbors in the building, including an eerie nine-year old girl who seems to know the real reason for Janet's fall. Lara soon realizes that she might have the same fate as her sister unless she can overcome the strange events that are terrorizing the inhabitants in Apartment 1303.
