Two friends get together for a weekend of golfing. Allan, a football hero, worldly and financially successful, and his quieter friend, nicknamed Byron, lame from a childhood injury who became a lawyer but who has never left home so he can care for a mother with Alzheimer's. During a long night of drinking, the fault lines between them start to show. One of the largest: the two men married sisters, though Allan married Peggy, the sister both of them loved, and Byron had to settle for Annie. Out on the course the next morning, Allan suffers a stroke. He loses control of his life, his wife and his business empire, which turns out to have been built on lies and the illegal drug trade. And Byron has to suddenly face his own weaknesses and strengths, his chaotic relationship with Allan and the Winter sisters--both the one he married and the one he believed was the love of his life.
