Every family has its problems. But even among the most troubled, the Plumb family stands out as spectacularly dysfunctional. Years of simmering tensions finally reach a breaking point on an unseasonably cold afternoon in New York City as Melody, Beatrice, and Jack Plumb gather to confront their charismatic and reckless older brother, Leo, freshly released from rehab. Months earlier, an inebriated Leo got behind the wheel of a car with a nineteen-year-old waitress as his passenger. The ensuing accident has endangered the Plumbs' joint trust fund, which they are months away from finally receiving. Meant by their deceased father to be a modest mid-life supplement, the Plumb siblings have watched its value soar along with the stock market and have been counting on the money to solve a number of self-inflicted problems.
