ALAN (RANDY SCHULMAN) is a successful classical music critic as reflected in his spacious Portland home. His wife SARAH (DIANE DALTON) is an obsessively grieving woman, struggling with an unspoken tragedy, even after months of institutionalized therapy.
Upon Sarah's release, Alan forces Sarah into a trip to Italy. He has already arranged for a house sitter in KELLY (LINDSEY HAUN), young and lonely for commitment and the better things in life. Kelly is quickly joined by her younger brother TIM (RJ MITTE), and her trashy-boyfriend JESSE (BLAKE BERRIS). Its not long before the trio find themselves drawn into a web of disturbing revelations. Jesse suddenly decides to kidnap eight-year-old ADAM (MICAH NELSON) from the supermarket. But not all is what it seems with ADAM. There is nothing of him in the news, and from the moment he arrives, he seems to radiate innocent control over its hapless occupants.
Sarahs depression returns in Italy and Alan suddenly reveals a horrible truth. But that truth about a boy and the freakish accident that claimed his life, proves not to be nearly as disturbing as just who that boy was. Little Adam clearly in control now as Kelly, Jesse and Tim find themselves caught in a netherworld between hallucination and reality. Kelly and Jesse eerily unaware as they lose themselves to the house. Tim's future far less certain in a HOUSE OF LAST THINGS.
