Willowbrook tells the story of Ben Hancock, a washed out painter that has had a run of terrible luck. He is divorced, away from his young son, and unable to create anymore. When his estranged father dies, Ben is suddenly left with a large sum of money and Willowbrook, a mansion in upstate New York. After reluctantly moving in, Ben notices his luck is changing. He becomes able to paint again, regain custody of his son, and even form a romantic relationship with one of the locals.
But not everything is as it seems in his new estate. The house has a violent history and Ben's own past starts to catch up with him. He begins to see images of Willowbrook in its former glory and the unraveling of events that led up to a tragic night more than thirty years prior. He sees the ghosts of children that once played in Willowbrook's halls. Are they trying to tell him of what once was? Do they want him to make it right? Or are they warning him of some present danger?
