After returning from studies overseas, Fisher falls in love with Jimmy (Evans), the down-and-out son of an alcoholic father (Strathairn) and an insane mother who works at a store on her family's plantation. She tries to pass him off as an upper-class suitor to appease the spinster aunt (Ann-Margret) who controls her family's fortune, but when she loses a diamond, it places their tenuous relationship in further jeopardy. Burstyn is attached to play Fisher's mother.
Mr. Patton plays Dobyne, father of Jimmy.
