Given the question: Build a movie plot around this: What does Brad Cairn do? takes two weeks off from his job
The answer is:
Brad (Sam Rockwell) and Abby Cairn (Vera Farmiga) are an affluent New York couple with two children. Their firstborn, 9-year-old Joshua (Jacob Kogan), is a child prodigy to such a degree that he thinks and acts decades ahead of his age. He is nearly always clad in conservative business attire and demonstrating limitless brilliance as a pianist with a marked predilection for "dissonant" classical pieces.Joshua gravitates toward his aesthete uncle Ned (Dallas Roberts) as a close friend, but distances himself from his immediate kin, particularly following the birth of his sister Lilly. As the days pass, bizarre events transpire as the mood at the house regresses from healthy and happy to strange and disorienting. As the baby's whines drive an already strained Abby to the point of a nervous breakdown, Joshua devolves from eccentric to downright sociopathic behavior.Joshua causes a fight between his mother (who is Jewish, but non-religious) and paternal grandmother (who is an Evangelical Christian and who constantly proselytizes Joshua) when he tells his parents he wants to become a Christian. Abby gets very angry and swears at the grandmother, telling her to leave her house immediately. Joshua later convinces his mother to join him in a game of hide-and-seek. As Abby counts to fifty, Joshua takes his baby sister from her crib to hide with him, causing his mother to panic and pass out while searching for them in the empty penthouse above them, before he puts the baby back into the crib to make it look as though his mother was hallucinating the entire incident.Later, after discussing Abby's psychological problems with his brother-in-law Ned, Brad takes two weeks off from his job to look after Abby and his children. When he arrives home, Joshua has gone to the Brooklyn Museum with his sister and their grandmother Hazel (Celia Weston). Joshua frightens his grandmother by describing to her in detail about Seth, the Egyptian God of Chaos, and his violent acts. While they are at the museum, Brad watches a video tape...
