Long story short, there's a guy who can see ghosts out of one eye - they're real, and a very small % of the population can see them - and his partner, who clear out neighborhoods that big companies will be moving into (for strip malls, or office buildings, etc) for a living. The partner talks to the living, and the main guy talks to the dead. In the course of clearing out one neighborhood, they run into a group of teenagers/young-twentiesomethings who are squatting in this ruined old house, and they refuse to leave, and things go downhill/uphill from there, lol. :)
