When 15-year-old Billy (Harrison Gilbertson) is involved in an accident, he becomes comically unhinged, and soon his family -- including an emotionally detached father (Joel Tobeck), a resentful mother (Geena Davis) and an aloof brother (Harry Cook) -- is launched into a downward spiral of dysfunction. As the one truly grounded member of the troubled Conway family, Billy has to pull everyone together in Andrew Lancaster's bittersweet drama.
