The Cairn's (Sam Rockwell and Vera Farmiga) have it all: good marriage, nice apartment, a gifted nine-year-old son, Joshua, and a baby on the way. When their second child arrives, the young boy begins to resent his parents constant doting on his new sister. Suddenly, a series of tragic events fill the Cairn household with utter despair and unspeakable horror. The events leave the family questioning if it's all a series of eerie coincidences...or the calculated agenda of a sinister sibling with the perfect plan for revenge?

Sam Rockwell and Vera Farmiga star in director George Ratliff's uncomfortable psychological thriller Joshua, as Brad and Abby Cairn, an affluent young stockbroker and his wife, raising children in New York City. Their firstborn, the nine-year-old Joshua (Jacob Kogan) is a frighteningly intelligent child - to such a degree that he thinks and acts decades ahead of his age. Nearly always clad in formal wear and demonstrating limitless brilliance as a pianist - with a marked predilection for "dissonant" classical pieces - Joshua gravitates toward his gay aesthete uncle (Dallas Roberts) as a close friend, but distances himself from his immediate kith - particularly when Abby brings a newborn baby sister home from the hospital and unwisely alienates the young tyke. As the days pass, one at a time, the mood at the house regresses from healthy and happy to strange, unsettled and disorienting; meanwhile, bizarre events transpire. As the baby's whines drive an already strained Abby to the point of a nervous breakdown,
