Cathy (Julianne Moore) is the perfect 50s housewife, living the perfect 50s life: healthy kids, successful husband, social prominence. Then one night she surprises her husband Frank (Dennis Quaid) kissing another man, and her tidy world starts spinning out of control. In her confusion and grief, she finds consolation in the friendship of their African-American gardener, Raymond (Dennis Haysbert) - a socially taboo relationship that leads to the further disintegration of life as she knew it. Despite Cathy and Frank's struggle to keep their marriage afloat, the reality of his homosexuality and her feelings for Raymond open a painful, if more honest, chapter in their lives.
